I stated with a rough pencil sketch then inked it with a brush pen and colored it with watercolor and gouache on a watercolor postcard. Reference I used was this excellent photo - https://www.pexels.com/photo/tree-wild-squirrel-monkey-97827/ photo by Mike from Pexels.com
I uploaded a version of this that I felt was kind of a throwaway. Just dinking around and trying to get a feel for techniques. In the end, while I was happy with what I learned, I didn't think much of it as far as a completed work goes. But I couldn't leave it alone so I took about another hour and fixed what I felt could be fixed short of starting from scratch. Because it's a process, right?
Landschaftpark Duisburg-Nord, Germany. This abandoned steel mill is transformed into a industrial heritage centre and landscape park. It's a great location for photographers and urban sketchers.
