What kind of pen do you use? How long did you spend on this, well done with the intentioned/deliberate lines! Too many artists hesitate, when just going with the flow produces excellent work too. Make sure you keep perspective consistent throughout the piece would be my bit of feedback. :)
Nice bird's nest haha, but especially like the whiskers on the muzzle. That is all nice work.
I was using a mircon pen and I dont remember how long it took me because I made it about 2 years ago. Ive practiced my perspective a bit more since then, but I appreciate the feedback! Thanks for the kind words. :)
