6/10. I personally can't do any of that stuff but it wouldn't look too bad if you added a bit more dark colors to the left side. It looks unbalanced unless it was supposed to be like a black and white thing. Then you need a bit more black going to the left side lol.
You already used that one you need to think of new things you're getting old even though you're younger than most people
About the sig it looks like a fractal over a render but I might be wrong I don't know why people always think something is someones first I give it a 2/10 read some tuts or something
