Cel shade for robots?

One of the ideas I had from the very beggining was to make the game with a cel shade finish.
Part of the reason was that some of the games that I recently played were Valkyria Chronicles for PS3 and the re-release of an all-time master piece: Jet Set Radio.

The gameplay it's completely different in both games, but the graphics have a same basic core. In the case of Jet Set Radio, it was the second game that ever used this technique, but certainly the one that pushed it to the maximum for the time and brought it up to the map. Now a days it might seem a bit outdated and most of the graphics seem blocky, but if people can tolerate to play minecraft then there's not issue with it.

This is an image of the main character in jet set radio rendered witout and with cel shade. Clearly there's a lot of personality added to the character just by outlining the geometry.





In a more modern game, obviously the amount of detail that can be added is much greater, but the among other filters, the effect of it being a cartoon, or in the case of Valkyria Chronicles an anime, it's still there.

Another reason why we thought of approaching this style was because the faces in the characters are just plain animated textures and using the cel shade would make everything fit just right. Unfortunately we weren't very happy with the results Unity puts by default, and didnt have time to actually look for other possible solutions as they might just make the process to go slower.
