... So this is wierd, and it shows that it's your first thing, but honestly, not too bad for a first. First of all let's get the nitpick out of the way: this is DEFINITELY NOT dubstep. Anyway, on with the real review.
So idk what you're using to make this, so you're gonna have to excuse the accusation if I'm wrong, but just judging by the strange combos of synths I'd have to assume you're using a lot of presets, although not every synth sounds like a preset, so props for making some yourself if you did. Anyway point is, if you are I reccomend you stop. I used presets at first, and looking back I feel they held me back... They can still be useful for inspiration, especially if you don't understand the purpose of the synth, but it's generally a bad idea to use them for your final product.
The general notes and composition of this is nice, but in terms of synth design, most are simple but effective; some, mostly the basses sound like they must be presets, but besides that thumbs up I guess... Oh, and I can only imagine you made whatever sound that is at 1:02, because it sounds far too strange to be a preset. While I feel it's out of place here I like this. It's off-tune, but as it's used as a riser, that isn't too jarring. If you could find a way to make it sound more in-tune and then modulate it, you might have yourself an interesting dubstep synth.
Now we've got all that out of the way, it's time for the real REAL review... (lenny) It's really hard to judge this song on most aspects because not knowing the process behind it makes it hard to know what criticisms are warranted and actually helpful, however there is one area I know I can critique helpfully, and that is the percussion... Which honestly, for a first song again, you did a pretty good job honestly. These samples don't sound like they've been mastered to your discredit, but they are good, and if whatever you use has anywhere near the amount of useless trash samples FL Studio has, I must commend you on the time you took searching for the good samples; especially the toms. The issue is, as I said before, the samples don't sound like they've been mastered, and mastering is probably most important on your percussion. If you ARE using FL Studio, or anything else that would have these plugins I would seriously reccomend looking into learning to use Fruity Parametric EQ 2 and Maximus. If you don't have either of those, you should still have an EQ and a compressor of some sort, you'll just have to find out what they're called. Also, Maximus is a multiband compressor, something that can set different levels of compression for a low mid and high band of frequencies, so if you can find a multiband compressor, even better! Anyway, you'll wanna learn how to use those, which might have to be through your own experience... I haven't seen many people that teach others how to use DAWs try making free samples sound good, I've noticed a running theme of many of them just saying it's really hard to do that and sticking to their better paid samples. So basically, you're kinda on your own there... I make do with free samples, so if you think my percussion is any good in my music you can ask me about that, but otherwise that might be something you have to learn yourself.
Wow, that's a lotta text, but guess what? I'm not even done talking about percussion yet, it's a lot more complex and difficult than it seems... To make good percussion, the percussion needs to have an impact, and one great way in electronic music we can artificially exaggerate, improve, and enhance this impact is sidechaining. You may have already heard of this since basically everyone who's made electronic music ever seems to do it in everything, and there's a reason for that... It's because it's easy and effective. Sidechaining is when you reduce the volume of everything else when the kick or snare or sometimes even clap hits for a short time. Sometimes subtly, but usually quite drastically, sometimes even right to 0. There are many ways to do it, I used to use a fruity peak controller and link it to a volume channel and invert the input, but eventually I thought it sounded better to simply do it with automation clips, some people even do it with Fruity Limiter somehow. Anyway, you're just gonna have to find which way suits you, but if you look it up on Youtube you should see like 100 tutorials of varying quality with different methods. But guess what? I'm still not done, but don't worry! This is my final piece of advice. I can't tell if you had it on this, but this is just something I tell new people in general. On FL Studio by default when you open it on the master channel all the audio goes through there's already a fruity limiter placed in the bottom slot that prevents the volume ever getting into the yellow or red. This is good for not making your music earrape, however, it's not good for your drums. I don't know whether most DAWs do this, or if it's just FL Studio, but either way if it does; you should basically always replace this limiter with some other compressor that allows you to get your volume into the yellow, and maybe dip into the red a little for breif moments when things like heavy snares come in.
