The first one, the background doesn't match the purpleness of the stock. :/ The second and third, add less effects and junk. It feels like I'm struggling to see the stock.
Wayyyy too many foreground effects covering the render. Try adding some neg. space, it can really spiff up your tags. Read some tuts, too. (sorry for the crappy cnc, I'll edit this later, but I'm in a rush)
