Aji, you rock! A lot!
I would suggest making floor tiles get rustier rather than having random blood patches.
But the picture you've done looks amazing! This whole thing is great and I can't wait to see it finished. I wold suggest putting some reward for mudokons for cleaning if anyone can think of anything.
If you do make vykkers, maybe you could have a lab area too. Your choice of course, since you're doing most of the work
