@malhomsi I can’t give advice on the sculpting side of thing. However, I’m very familiar witch artist block (aren’t we all?)
Whenever I’m stuck with something I leave it be for a while and go do something totally different. Something fun that doesn’t any expectations of being great. Do a course I haven’t done yet, or create something simple just for fun. Enjoying the journey of it rather than focusing on the result. Usually after that my mind is clear and I can get back to my project and get much better results.
Hope this helps. Good luck Malhomsi! I’m rooting for you! 👊🏻😎
