really like where the base is going though! I think the main issue is the brown maybe. Not so much the rim (if that is what matches your army, I'd leave it) but on the main part of the base. Maybe you could go around with a colour that will compliment the purplish. Normally I'd say green but I think in this case it might take away a bit from the 'alieness' of the base if you used that. Maybe check a colour wheel for alternatives? Anyway, lovely bug!
