not bad its a lil small, and lacks depth, u need to add few adju layers wuld look alot better.The lil effects on the bottom looks cool jus add a bit more of that.The text placement could be better.
eh looks like all you did was add c4ds,change the lighting/add a light source, and text i guess people dont really like it because it doesnt really look like any real stock alteration took place
makes sense. of course i'm going to say i did much more than that, but if that's what you see, i can't change your mind...
you did a good job with the effects but i dont think this is the type of photo that looks good with them.
