Finally i finished the retopology. It was harder and took longer that i expected but im happy with the result. In the next step i will texturepaint it. I'm not sure if i do a animation, because topology is still a bit messy.
Overall i enjoyed this Project, especially the sculpting process.
Watch it in 3D on Sketchfab here:

You put a lot of work into and it paid off. Great job!
