This goes to show how bad this site is for GFX comments & ratings. It is either a 10/10 on a shit sig or just a comment that makes no sense just for the sake of a post count. FYI there is no blending in this sig.
On the other hand;
It isn't bad for a beginner thats how I started out (with the 2 pics in the back covered by a render where they meet). However, I would suggest lowering the glaussian blur you have on the sig.. or whatever kind of blur/lighting effect that is. & always try to use solid text, the outlined text (where letters are see through) usually dont look great on most sigs.
5/10
