Not your best, but unique. I cba to find the original stock, but seeing kitten's stocks, she looks like she uses strange perspectives/distortions to elaborate on her emotion/s.
My notes:
- Bottom lip is cut short and is big (intended or not, I couldn't know).
- Top lip looks a bit strange, there is too quick of a transition to the top lip from your left over to your right. Shading there looks a bit distorted as well.
- No eyebrow to your right (")
- The hairline looks a bit rushed, some parts look a bit odd and angled/unnatural.
- Shading in the neck got me confuzzled.
Would be easier if I can take a quick ref. from the original stock, but GJ overall. I like the eyes!
