its OK, but the background took away the focal point there, garchomp, the text is a little bad, maybe try a text generator? the bacground is ok, + you need a border to top it off.
The background is kind of boring, It tries to look good but it kinda fails at it. I like the fact that you are trying to make it blend in but it's not really doing the job. Make the render (Garchomp) be in the middle of the signature and try keep effects/smudging/blurring off it. Also your text is pretty basic and I don't like it that there is a light blue stroke on a black text, it think it should be the other way round with another font and smaller text that fits in with the signature. Add some lighting aswell and finds some tutorials about that and text, I'm still pretty crap at text myself And don't use a text generator, They don't really give you good texts.
Overall, Decent, Can do some work, Also add a border. 3/10
