Only advice I can give is:
Keep sculpting until you are satisfied!
You’ve picked a great subject / reference material — it has some basic shapes, understandable shadows, which are great to start self learning.
Important thing you can do is save your work and do it again in a month or three to examine your own progress.
Another sub-exercise idea, after you will finish this version, try to come up with a totally different color scheme, not present in the reference image — this can help a lot because you will force your own creativity to kick in, instead of just making a copy of something, plus good coloring is deceivingly hard to pull off…
I would mostly do more of what I am already doing, spending as much time as possible surrounded by nature, for me personally — woods. Or, riding my bike even more… Learning and reading even more, plus programming level 9000 on the side.
I could visit Iceland and Japan without overthinking it too much…
Oh! If this “needs are met” applies to others too, then I could spend more time with people that are now grinding hard all this working or parenting life. If it doesn’t apply — then I could try to do my best that it would.
