Honestly, it's too big to be considered a signature. I think it has way too much spacing in it. The colors need blended more. When I say blended, I mean through gradient maps with layer settings and photo filters.
By blending do you mean the smudging behind the render? Because I made 3 copies of the final image, added gradient maps, and then used some blending modes to combine them. Heres the one without any maps. What I essentially did is use the 3 map layers, combine them, then I took the render and changed some stuff and put it on top of the maps, then added the green bit on the left. Obviously the smudging behind the render is not exactly the same hue as the rest of it. Suggestions?
Try using gradients with different colors and setting them on different blending options. I think it looks pretty nice. Nice use of pen tool (pretty sure its a pen tool). Like some people said, border looks better. If your going to keep the border, I think black would look better. Nice job . Btw, aren't you an old gfx artist?
Wow, your pro i'd slap a 10/10 on that ass...God damn thats good, rate mine, this is my 2nd try, i think it looks good for a 2nd try.
