Hi.
Thank you for the reply.
I've looked up pillow shading and tried to change that so that light comes from above on right. Tried to take away the black outlines as well.

However, if a person is looking at a screen for example, wouldn't it be natural for it to become pillow shading? looking at old snes games it seems to be pretty much standard way - that the light seems to be coming from the front.
Also, black outlines. I see you reduced the amount of "green" AA - and that looks better. Less jagged. But black outlines also seem to be pretty common in pixel art - to make it stand out from background. How to think about that? is it better to go with a whole outline round the character and try to not have it within the silhouette?
Thanks again for your advice!
