Well, sounds like pretty interesting thing to do, so rewarding in itself maybe. Is it published on github or elsewhere?
Also, as someone doing graphics programming mostly as a hobby, I think a good thing to do is to learn the artistic side of things (to some extent), might give you some advantage.
Yea the artistic side of things might be good to try, I do like the idea of exploring toon shading more.

Sounds excellent! And don't hesitate to publish your work.
That is not to say that one is intrinsically better than the other, but for a technically-minded person (== any programmer in this case), the way Houdini works will make much more sense.
Learning either of these tools is not an easy task, but I think that starting with Houdini will feel more natural in cases like yours (SE background, interest in interactive graphics).
You can email me (see my profile here) for some more Houdini-talk!
