I just made this new signature that has Lucario on it. What do you think of it?
The left side looks decent, but...the right side is extremely dull, and the text is horrid.
Not trying to be a dick about it, I'm just honest. D: Try putting a border around the text so it stands out, and possibly make the sig smaller so there's not as much wasted space. Other than that, good work! :)
The render is messy, and doesn't flow with the rest of the signature. It's just sort of... there.
Put an outline around the text, maybe change the color to something that reads better on the background. See what you can do to blend Lucario with the background, I'm not sure which program you're using, so I dunno what to tell you there.
It's a good start, tweak it, & it could be awesome. :)
