Oh wow that came unexpected! Nice work. Reading your description, I got to admit that I would not have guessed that it's an owl girl. Of course the mouse, the snake and the claws are smart hints, but probably to smart for me.
Minus 0.5 stars because it's not a fully fleshed out drawing. But other than that I can't see anything wrong.
Your lineart is amazing. Great & appropriate line weight overall.
Thank you for flooding with us. ;)
Looks great! Is this based on a photo?
The linework is crisp and smooth, and I think the eyes are done well. I think the thickness of the lines around the nose could be slimmer, but otherwise I can't fault the picture.
Cheers for taking part, I thought this was going to be a really weak art forum activity.
