Text needs removing. Background doesn't look bad, if a bit, simple but the stock really doesn't blend in at all. You've got no light source, no shadow so there's no depth. Could be good but needs a few changes yet.
I see a little cop out light source. That little soft brush at the top doesn't count. Text looks meh. And, to me, it looks a tad boring. Nothing too eye catching.
BG is ok, as said above the ninja does not blend in at all. Text is meh, and the flow is a bit weird . But the sig has potential .
Heh, I know text doesn't look good, but it looked worse without it. and I guess I didn't put enough effort in the lighting, I'll remember that for my future tags. Thanks for the feedback, here I tried to improve lighting: but I think I'll move on to something new instead than making more versions, and I'll try to keep all that stuff in mind
Text needs to go + render needs to blend alot more. Looks like it's just been put on. Other than that the BG is nice.
No depth, Background looks blank. Render doesn't blend and the text doesn't fit with the signature at all.
