Thanks a lot! I'm starting to realize I am not very great with shading things, so I gotta brush up my skills.

I love how close this is to the original character. There a still some tiny crudities about the rendering, but it's a great tribute nonetheless!

A real shame they killed him off. :(

Yeah, greys against warm or saturated colours are to be used with caution. That is not the worst part here though. It works as far as value and hue goes, just not that great, maybe it would work better if it was a tad lighter, but then it might be too light for the glasses and hair.

Thanks for the critique! AA is mostly a trial and error thing for me, I should practice thinking about it more logically. I was kind of fond of the grey on the skin, but maybe stuff like that is better in smaller doses, or among more of a variety of colours, OR not inbetween two warm colours.

Nice and clean, but some things that are a bit off.

I don't think the grey on the skin works particularly well here.
Single pixel AA does not do much on long shallow slopes like the inside of the jacket and down the arms.
