Ermm...looks like I got skipped, so I'll go again. Basically, all four are awesome. Colors, tetxt, renders, effects, all blend very nicely. 9.5/10 on each.
lol @ bruce is loose, i like the overall colors and nice choice for a render its definitely something i dont see often... 6/10 bcuz the vadar one sucks
nice techy sig, with a nice finishing touch on the animation. 7/10 i think u shud make the quote stand out a bit more, and add a boarder.
lovin those sigs, the broken glass type look is nice but a little over used and it seems you used the same text effect for both sigs which makes me think you ran out of ideas, for most of the first sig you can hardly tell theres a border there but maybe thats the idea i dunno im just not diggin it... both are overall awesome imo and deserve 8.5/10, possibly change it up a bit in future creations and im sure you will get 10! edit: possibly try to focus on not making you're font stand out so much from the rest of the sig as well
it misses border and the "if the name doesnt bla bla bla..." should be in pixel font also it needs better brushing and the text doesnt blend very well 7/10 anyway
Render and text and colours all look good And the brushings preety sweet, it seems to flow preety well 8/10
9/10 I love it, especially the brushing. The only thing I would suggest is make the border white and set it on color dodge and lower the fill.
The red-eye one is really cool. and the raven one is missing something, dunno what though lol. 8/10 for both
