Little green troll
The original pencil sketch was too small, so I enlarged it by copying the image into my wordprocessor and then blowing up the image. I then transfered it to my watercolour paper, this time using the windowplane as my lighttable.
I had some gouache paints left on my palette. I re-wetted them. They lose a great deal of their opaqueness when you use them like this, but the colour is still quite vivid. In fact they act like watercolours and work very well together with markers.
The reference I had was out of a youTube video about drawing chibis. I am however not so much into manga and chibis, and you might notice that the result is looking more like a troll than a chibi.
