Nice models, but make the wasp bigger, and stick with the theme of "empty joints". and get the colors right.
And the Caterpillar looks good, but Blockoman is right, it does look more like a centipede. Also, since I've been busy with some other things lately, I haven't been able to work on this much. Hopefully I can get the production speed up sum by next week. (yes I'll be busy this weekend D: )
