I think we hand out enough medals as it is, tbh.

Improvement should be it's own reward, seeing present stuff you made compared your early works. If there's a difference in the two you should feel proud, if not then it should just be motivation to work harder on becoming a better artist.

I'll admit getting an award is a good feeling, but getting positive feedback from CnC can be just as effective, so I don't really see the need for this particular award/medal.
