My pencil concept

This one is a little sloppy, but it's the only one I have scanned (scanning is a little complicated on my confuser, long story). The proportions are a little off, especially on the lower one. I have a nice camaro I'd like to post shortly.

Leviathan is the name

Nice work! The rear reminds me a bit of a viper. One thing I'd suggest is to try to get your lines a bit smoother and more flowing.
