THe chimney, was the last thing I added and the initial sketch don't had one. Although I liked the form of the top, you are right with the structural problems ptoing. I improved it and twisted the chimney, maybe this adds also a bit charakter to the house.
I further made a slight color/contrast edit, which one is better at your monitors?
And the charakters eyes, yeah there is also something which bugs me, but it's pretty hard to say what it is, maybe the form of the face just don't work. I tried out lots of different things, although 3-9 seems to look pretty odd. I worked on from 2 and also changed the face shadow and hair form. I think 13 looks best, but I don't know if it looks better than the original. What do you guys think?
