I like the cleaner beetle very much. Colour, shape and pose are wonderful!

The skin of the others are still an early sketch I suppose, because it is very flat. The flying model needs a sort of contrast on the skin, a second colour. Maybe, the next step could be adding small lined drawings or signs overall the skin, similar to the beetle, but with smaller lines.


What sticks out is the hand of the rat. It should be less straight in idle pose, and it doesn't grip the sword close. To solve the latter you could make the sword and its handle bigger.
