Straight away you establish the mood quite well, and I love that uplifter, it's structured and effective. I think it has a little too much release in the times it is re-used, It's nice, but the high frequencies get kinda annoying when sustained for so long. As well as that it almost starts to sound a little detuned as it fades out, not sure what causes this, but it is annoying...
Then the electric guitar comes in, awkward thing is I really don't like electric guitars, but I can't lower your score just because I don't like them. So it may be a little difficult to review this since the electric guitar is your lead... What I will count towards your score is I'd say it's a little harsh on the ears, turn down the distortion (if you're using it) a bit, or maybe just do some softening with a Parametric equaliser or something... I wouldn't mind it being harsh so much, if it wasn't for the fact that it's the lead instrument, if it's going to be played for so long you can't make it the lead...
Then for quite a bit we just get that electric guitar playing with some percussion for a bit too long to me, just a small problem. Then I noticed another problem, the percussion itself. The patterns aren't bad, but the sounds themselves are. Sorry if you didn't have access to any other percussion sounds, but I do have to make this a criticism. With a name like "Titan" I expect a pretty slow drum loop with a lotta momentum, which is what you did, good on you. Problem is that something that's supposed to be slow and powerful needs deep, hard hitting snares. Here we have light, high pitched snares that don't really leave much of an impact. Even just adding some reverb can make a world of difference, if done well.
The general mood's pretty good, the base sounds are slow, but the backing and additions are fast. This really nails the mood of something big and powerful, just like the title suggests, "Titan". Another nice detail is the base sounds are also lower, once again giving the mood of something big, but the additions are high-pitched adding a bit of a mythological feel to it.
I quite like 2:08 though, here the "momentum" of the track really shows, although there is less sound. Everything comes and goes suddenly, which usually would be a bad thing, but here it really puts an emphasis on the silence; which in turn, emphasises the "impact" when the volume returns in a fashion almost like call & response... I also noticed sometimes sounds were subtly "sidechained" back in, which really shows attention to detail in your volume management, and attention to detail is probably the most effective thing you can have over all other composers in music.
Finally, a little nitpick, the end is silent for too long before ending. Just a little problem, but silence in music is used as a prompt for the audience to take a moment to reflect on what they just heard, which is why people have it at the end of their songs. They keep it short though, so you don't get bored. It's not a massive problem, but it's kinda annoying when I'm listening to it on loop... =/
If this was more personal, for the electric guitar I'd dock half a star, but it isn't so I give it 75/100.
