Thanks for the input, I see what you mean! As for the right wing, it did have lineart at first, but it seemed to distract from the head - I guess it would have been better to keep a lighter outline after all.
Cute little critter! My only qualm is that the wing to the right looks more like a third arm or a second tail than a wing, even though it's probably anatomically accurate. The selout's a little weird too - it feels like you're trying to have it match where the shadows fall, while simultaneously varying the line thickness as a sort of foreshortening, but it doesn't quite accomplish either.
