Effort: 2/2 - i see that you tried.
Look: 1.75/3 - Idea of the text is cool, but I don't see it working well in this sig. Splatter is actually well done, but render needs to be blended better. with a JC, try to choose similar colours to the jersey with the logo or change the huge of the jersey. At least you tried though and thats a thumbs up for me.
Creativity: 1/1 - Also like the subtle bg render you got in there
Overall: 4.75/6
