Smells Like Sheet in Here

Greetings and salutations fellow pixel mongers, if this thread has been erroneously created or misplaced, I apologize. Long time site/forum lurker (Talkin' since at least 2009) finally creeping out from the shadowy depths and registering to spew forth this glob of digital vomit unto your eyes. Asking for constructive critiquing and helpful suggestions before I finalize and sheet them. The characters depicted below are one-off "rough drafts" for a long-time planned/shelved game project I've only recently begun to re-explore since I've got more time on my hands than an overstocked watch salesman.

Quick descrips.


1. Stein (A hyper-intelligent A.I. who acts like a ditzy cheerleader.)
2. TS-17 Gravedigger (Stein's armored robotic shell.)
3. Thanatos (A grim  reaper and a drunken a$$hole.)
4. Dahlia (A vampire assassin.)
5. Mr. Zed (An ex-P.O.W. given supernatural abilities in an experiment.)
6. The Stitch-face Killa (A homicidal maniac.)
7. Frostbite (A lycanthrope with a high powered revolver and a freeze ray.)
8. Beez L. Bub (A male demon with lightning magic and a railgun.)
9. Lucile Ferr (A female demon with fire magic and a napalm bazooka.)
10. Skeletank (A cyborg tank with a large demon's brain.)
