first one is great, love the vectorwork and brushing, hell everything about it, 9/10 second one, meh... render+text lack flow with rest of sig, nice brushing though 7.8/10
Top one: I like the colors, the pattern and the was you add the sig to the render. Overall good job, 8/10. Second one: Dont like the colors, but it would be good if that were changed.
9/10 on the first one its got a good font and text effect, and the background works with the render 8/10 on the second one becuase i just dont like the font as much on this one, but good brushing other wise
