It looks better on blue (colder), and the photo is slightly better, but I have to agree with Ross that it's too soon - especially with no real change to the design itself. I'll give you a point higher than last time though because it does look better.
this looks exactly like your first submission. auto-white balancing an image so it appears brighter than the original and changing the shirt color does not constitute a resub.
