Pretty nicely designed with the overall image, I do like the whole janky feel to it though, and the nice use of blue with the touch of green reflecting light really adds the insectoid coloring to it.
However, the wings could use a more visual effect instead of little etches to indicate the movement, and they feel like they simply lay on top of the fly instead of actually connecting to it, and the mouth feels a little flat, even a new background could help, the painterly feel / watery feel doesn't seem to fit the way the fly is done itself. Pretty nice though.
