SgtNasty: I totally agree! I feel like my design was missing something, but I couldn't figure out what. That helps a lot.
Here's a mock-up of some cool designs I found on Google Images. I'm partial to the one on the right, but the left one is also pretty interesting. What do you guys think??
and a proxy shot to check scale/proportion. Also... I feel like the shaft on the proxy model provided isn't really long enough... but whatev's, I'll just stick to it anyways.
