A bit overburnt... not feeling the plain render and the bg... maybe try a different render that has more structure to meet that bg. This way 6/10 your second one is much better, because of that great render only... very cool effect of split ring.
The first one's a bit plain, though i like the softness of the sig. Only thing is the render quality - it looks kinda sharpened too much to flow okay with the rest of the sig. 6/10
1st I dont like, fg doesnt go with bg.. 5/10 2nd one awesome, especially color choice of text. 8.5/10
8/10 7/10 6/10 rate both of them SEPARATELY. i hate that ".../10 overall" sh*t. i have 2 sigs so i want 2 ratings
