Nice sketch and the idea is very interesting:) I remember the other characters also like the dragon, they all share the same concept.Emotions take shape and manifest in the physical world. I share this idea and the first i red about it was at the Corum Trilogy of Micheal Moorcock. It is a fantasy series where the Chaos Gods take shape and power by the people feelings. The more the negativity more power. If you ever have time read them, i think you would like them:)
I searched for the story and found the plot interesting. I have yet to find an English version of the story though. In my search I ended up getting 20+ pdf files related to drawing and photoediting while I'm at it. Didn't accomplish my main objective but I got productive nonetheless. Thanks for the recommendation :D
