no, and no offense but you made it worst
this is an example of what defiant is saying: (made this tag long ago)

the text blend very well with the whole signature because the color matches the signature. Let's say you have a signature that has a lot of blue in it, and the only thing red is your text. It should be blue as well to blend in. You get it now?
other tips:
-Don't keep your renders that big, make it a bit smaller but not small enough that it fits on the canvas
-Make your text smaller, and near the render. NEVER make it near the corner or bigger than the render, or even both. look at the signature above for an example.
