Looks great, especially the Keelerak Spider Mistermind. I hope you will edit the weapons too. You can do the same thing as the original Doom devs and just turn pictures of Bionicle blasters seen in first person into sprites.
They used these toys for the shotgun, bfg, minigun and plasma gun sprites
oh yea i know those are cool toys
there were some sprites for first person weapons already when i joined the project but they dont look so great yet (they look a bit like photos that are poorly chroma keyed) so i will have to redo those
