Add some lighting and darker areas to bring out a focal and natural feel to it. Right now, it's rather flat and sort of confusing. Good colors and I like the simplicity though. Just needs a few tweaks from what I can see.
Wayy to monotone. Try making the tag's background and effects based on your concept/stock image. Sometimes you don't have to, but coloring the whole tag ruins it. Try a mixture of dark and light colors with some more ----- effects. The tutorials in the forums above are really good help, trust me.
not bad the colours dont really look that good.the smudge or the effects dont look right. The text could be much better and change the placement for it.
