the first one needs some work with the overall "flow" of the sig. It just seems like a bunch of random pieces put together with no overall goal in mind. Every piece is alright on it's own, but they don't seem to go together. There is no focal point, and I'm not sure what to look at. Try to find a spot that you want people to focus on, and have that part the most detailed. Then mess with the lighting to highlight that part of the sig. As you mover further away from that point, have less detail and make it all blend into the next element. the second one is much better. The focal point is very obvious, and the blending and overall flow are much better. Keep doing what ever you did on that one, and you'll keep improving in big steps.
slickcj99 that last one was a step backwards but your second one was great. keep going in that direction. sioee562, try deviantart or photobucket. imageshack and tinypic are good too.
