Congrats for your first large scale composition

Ok now for some constructive criticism:
I noticed that some of the textures become repetitive and static after a while.
Also maybe you could try varying or playing around with a theme instead of repeating it. Like what random14's suggested in his post, except you can use
both of those motives to give some variety.
Have you heard your piece performed live? Doing this will def help a lot.
I actually have to agree with Worcnagrom that 'Fire' sounds noticeably a little too similar to the FFVII battle theme.
