So what I think can be improved on, the shading is very light. The bird feels slightly two dimensional. as well with its perch. I think that the highlights on the feathers should be more loud.
Your lines are clean, and the background is very beautiful. I really love seeing animal images and people trying to learn from nature. Please keep up the good work!
Wonderful drawing. I love the rich bold colors. Fantastic attention to detail and an outstanding job! Thanks for sharing.
