Outcome from Time Shift Tutorial:
Very good. I like it! Far better than IronMan signature.
Nice focal, blending, smudgeing, bluring, good light source, and I adore that white line that goes from his arm to the text.
Maybe you shouldnt use fire stock, it doesnt blend that much in this signature as it blends in the tutorial. Maybe you should decrease opacity, a bit?
And yea, space stock rocks
