Wow that's amazing, the things in don't like are the wihite lines (they disrupt the flow), and the A on one of the circles, but great job man..
its nice but i would put thoes 2 pale orange orbs more colors that match with the tag. And id also burn the sides and dodge the focals to accentuate the lighting and blur the outer parts and sharpen focals, and blur the lighting to add some more depth other than thoes minor fixups its amazing
Nice job on #2! I agree with Rsruser, the white lines are weird and the A on one of the circles.. The 3rd one is too bright, making some details invisible (but visible in the first 2 sigs) Gj!
