its not too bad, but the render doesnt fit in with it.
change the background colour because of the outline of the sprite and the renders large black areas, the background makes it hard to notice
your text could be better, quite hard to read
everything else is pixelised and the dragon doesnt fit with it
6/10
fix the points above and it'll be alot better
also, dont add a background or effects, it'll just confuse your sig and make it worse
