Nice... Indeed...
Yo man, Do you work for CAPCOM? Lol, Cuz alot of your music sounds like something that came out from 'Devil May Cry', not this song, but you know... the others. Maybe you should send emails to Game industries and show em what you can do, cuz after I heard all that stuff (Specially MGS themed one) I think you could be on the top Music makers for Gaming. Look at the bright side... its not as hard as modeling, drawing, ect...
As for this, it sounds tight, sounds like if someone was trying to escape or something...
