It does look quite good, obviously if you wanted it to be perfect you’d do some erasing of lines getting in the way so i won’t bring that up, in a lot of places it is kind of messy, so as i mentioned with erasing, it is important to draw carefully and lightly and erase mistakes. A good skill to practice is very light drawing, so once you have the sketch done you can go over it darker, that way you can erase mistakes without it leaving a mark you can’t fully erase. The bone/wing i think needs to be moved a little, it looks like it starts right at the butt which while looking at the wing at first- looks fine, once you take a second look you can tell it’s off. Getting position can make or break something sometimes, so just do be careful on that
that’s all the feedback I’ll give for now. Hope it helped!
