You should go around those pics of piccolo and trunks better with the lasso tool, or go around them with the eraser tool and with wet edges and 50% opacity and after a few minites you should have better lookin pics. Also those pics are rather low quality, really try to get high res cell captures.
1m4 that a pritty classy background, as you said the background is only temp, and it is great, i dont mean to nite pick but aint the faded vegeta pic a little squared of and you should move it to the right and up abit so it looks as if the rest of the pic is hidden under the black.
Yeah, i know its nothing hard and the effect is simple yet at the same time effective. The colors are a bit blands so try to spice that up. By the way sorry about that.. It look like that tut at Subliminal Genesis ( http://subliminalgenesis.com/ ) Just modified a bit.
*Edit* Well, What do ya know I was right :] Well at least I think so
