Excellent... Be very good for a desert or swamp map. Shad Palace could use some music of its own, I guess (aside from the ending theme). Foamy is working on Run2 last I heard, might work alright there as well.
The first one is a bit repetitive for my tastes but it should work well as background music. I can't help but visualize challs when I listen to it. Does that map already have music? If not, I think it would fit perfectly there. It also might work well in the tomb in world walker.
The melody in the aleyesu remix is way too quiet. Also, I would prefer it if two of the samples you used (sounds like some kind of sitar and some kind of pitched drum) had less sustain. They sound a bit muddy, especially together, but that's just my opinion. The track should fit well in shad palace.
You have a knack for percussion. Might I inquire about your musical background?
