I like the sparkles a lot... the rest of the image seems a little barren by comparison though, and I agree with Vince, the figure looks pretty out of place, and the text doesn't stand out enough I think.
thats just a really big ass brush over a dark bg with a lighter color to get the bright spot in the bg then a fill over it with some random trendwhore pattern and then either a bryce render or sinedots filter around the stock topped off with the scatter effect on the airbrush ...lol sorry went on a rant
This one is much better than the other one. The pic would look better if it was a lil bit larger. The colors match very well and the tex blends. I can only see that the uniform looks a little bit bright and kind of like coartoonish.Also it is semi blended but if you lowered the stock opacity by maby five it would look better.
