not bad. sharpen focal and blur BG. gradients a bit too strong. nice text tho i suggest reducing the text size.
Signature looks pretty good to the eye, worked out well, there are a few points that might help you make better ones. Especially the focal point (the wolf) needs to be more up front and 'splash' out. Background and effects are simple, yet still good, however I think it's a c4d or another effect that is just above the wolf' head and seems a bit weird. Some more colors would be great; either work on a colorful tag or make it B&W, these colors seem a bit odd and I don't like it that much. If you insist on keeping these colors tho, and you want a border, I think a white (inside) border would fit in more (also try 2px and see how that works out). I'm not good with text, it's a large signature so a tad larger text. You might want to try a little less 'tech' font. Good job anyways.
