I like the spin on the theme! Going for a bunch of epic boss themes is something not many people are doing so good job! The songs feel epic and dangerous and definitely capture the mood of battle. My only gripe is the mixing could have used some love. In particular giving the drums some more volume and presence over the other tracks would help them out a bunch because the breaks are great! It also sounds like the sounds in the tracks could use some low end cuts to let everything breath. This is a cool OST keep up the good work! : D
