Unfortunately I could not work on this for a while because I lost my Internet for a week.
So I have now The rough base finished. The next step is to polish it to a good level and after that go to colors.
I changed a few things about the idea and hero shape of the character but it works good I think ^^
The method to paint like in the class was a bit hard for me and took a lot of time. For future characters I will switch to a line work after I have the silhouette because this feels easier and faster.
