Seriously guys, I know the word 'cel' comes from 'celluloid/cellulose acetate' but it's abbreviation doesn't have two 'L's.
This is looking marvelous so far .I would have it's beak cast a shadow though. I think it had a certain charm without the aa. I would say that cel-shading is to shading what aliasing is to a continuous signal and so leaving the aliasing would synergize both aspects. It doesn't bother me much though, I know it's good to mix & match, and something like this should be entirely at the artists' discretion.
I like the colours, they portray a sunny daylight environment quite well.
