I think it looks pretty kool. Though the words stands out a bit, maybe you should overlap some gray over it to make a more "whispery" effect if u no wat I mean. Other than that, great job.
Yea I see the Like/don't like thing your talking about. EH, I don't really know what to say to be honest, its hard. Burn the bottom left a bit, and sharpen then fade sharpen. Plus erase up the arm just a bit.
I personally dig the way you made him a part of the background, it gives me the impression of one of those time-has-stoped moments, very much like in the very cutscene. But the text doesn't fit well, imo. If you insist on having it, it should be in the left corner and not disturb Riku's movement. Just saying. x:
I can see where you're going with it. You didn't have to smudge his arms off though. XD Sharpen up Riku some so he stands out. Add some photo filters so that it adds some sense of depth to the rest of the smudging, particularly the less colored parts. >D
