I think more can be done with this. It looks like a render was put on top of a background. Try blending a little more and adding cool effects.
Way too boring, you should bring out the effects more, and take away some contrast, also try fixing your text by making it have a colour from the signature itself in the text. When the colour of the text is a colour depicted from your work it really makes the text bold and look strong instead of just a mess.
There can be a lot done to the sig being a stock or a render. Get a nice c4d that matches the colors well and place it into the sig and see how it turns out. Try get better lighting and blending.
I wouldn't care if it was the Mona Lisa. You're not going to get any appreciation if the signature doesn't look very well done.
Its nothing compared to other paintings imo. I have seen it first hand, and it wasn't that amazing compared to the works of otherz. Anyways... Very boring, bad text, and bad background. Try looking up tutorials on Youtube, Gimptalk [if you use gimp, or just use my good 'ol friend Goolge.
I dont really like it. Well, i dont like the backround atleast. You know i have a friend named brendan roy.
