It's nice, but anatomically it wouldn't work. The wings aren't angled well to allow it to fly or even lift it off the ground, and the Scrab alone isn't an aerodynamic animal, and it would probably weigh too much to sustain flight.
My suggestions:
-Bigger wings (like, way bigger. Like, each wing is twice as big as the scrab itself)
-Put them right-side-up, or put the wings parallel to the ground.
- Give the wings a bone structure. Wing skin needs a frame to support it, even with insectoid wings.
-Maybe tweak the Scrab's anatomy a bit, since the species your using isn't aerodynamic at all.
I do like this idea, though. It's very interesting. If you'd like, I could draw what I mean in my points if you would like.
