Not bad as your first siggy , but try to not make your siggs colorful more than it should be .. i guess everything else is cool once you edit the colors.
Don't listen to the people enig! It's a really nice siggy, colors are really nice ! Only thing I'll do is adding a rainbow gradient in Hue mode in a really low opacity so the colors aren't thaaaaaaat strong, try it. And you can aswell work a little bit on the lighting. KIU
I believe Edward just joking Shadow, just ignore him. D;
For the sig itself, you forced the light so it looks overlighten. Liking the depth and also add some clipping mask and filter imo. Otherwise is cool. GJ
