I'm still noticing a lot of crosshatching... The colors are a new aspect to me, so I'm not sure how to critique them... The striated patterns with the crosshatching work really well... Have you considered doing spiral patterns or perhaps circular, dotted patterns within your works? This is spectacular, by the way. And, to that end, I have to comment upon the consistent and almost organic form that the tumorous lumps take. They look awesome in that fustercluck of a colony.
