I did this on Tannim's OC 5 days after creating the rough of "hot", because I wanted to do it in colours and to create some fire I always failed rendering before.
That's strange. At the beginning, the fire looked SO awful ; then, I worked on it, worked on it, worked on it, adding touches by touches some red, some yellow, some black... And the result astonished me, I must admit. The number of strokes required for the pic astonished me also, I learnet I spent 11.000 on it !!!!! 0.o
The dragon still doesn't look good despite that work, though.
