This is really cute. I'm a bit biased, though, because I really love owls. I'm having a bit of difficulty telling if the picture is completed, though. It seems like some of the wings are there but it's not finished, in a way. It makes me question if you hit the edges in your sketchbook and then covered it up with the leaf texture. One of the ways around this is to either purchase a larger pad or to take multiple pages and use masking tape to tape them together on the reverse side. This way you don't have to sacrifice making your drawing smaller to fit on the size page you have.
I checked out your instagram, and I think you cropped the picture a lot better there. There is so much excess space that takes away from the focal point. The leaves also feel like a massive after thought. They are just a texture brush and it would have been interesting to see more than just maple leaves. The brush or image used also is fairly pixelated at larger sizes, so it does not mesh well with the crisp, gritty pencil lines.
What I would love to see from you next is to do a study on furs and feathers since instead of more accurately portraying those textures, you are really just representing them with lines or penciled patches. I feel that if you worked more in that direction, you could give your work a more realistic touch because right now it comes across as a little lazy. Push yourself!
