My work :D rate

Remove border.
Darken the right corner more cause the light comes from her right shoulder.
remove the light that comes on her left side, the light comes from right and only.
That square with text, doesent go well with the theme.
Use simple text with outer with black outerglow 1px.

i see green and purple there, green doesent match with render nor background.
Use color balance option to optimize that "error"
it seems pale, no depth you could use some sharpen and blur the darker side to gain some edges.

Overall i wanna see your next work,considering my critique.

i think u should change text's place and color on right doesnt fit with whole action in the sig
