Wow, I didn't expect you to go this crazy with that xD Well anyway, they're nice. All that red in the third one is like "WTF MY EYZ" though. Maybe add a bit of pentooling nea his left arm in the first one. Also, I love the effects behind his right arm.
Uhm. The only nice one I like is the second one. The thirds color balance is way off. Fix that. And do some hue/sat for the colors. The first needs more. Too dark, add a stronger light source. And compo on the total right needs a bit work. Cut the border off, way too 07 =\ And the image of Tidus itself isn't in that good of a quality. But some light brushes in there of like light pink or something in that hue. I've seen more godly work from you.
