I would look at it more as of a road rather than destination.
Something to note, being as technical as you could wish for (in Blender) will not help you too much with character modeling. Actually being artistically inclined and well balanced in terms of anatomy and concept design would be much likely a more preferable skill.
And it’s always a case of getting better at all of these.
My breakdown of the skillsets involved would be:- Technical knowhow to be able to (efficiently) achieve your goal.
- Good knowledge of anatomy. Weather it’s a fantasy creature, stylized character or a realistic human, the better your knowledge of anatomy the better it’s gonna look at the end.
- Solid sense of concept design, still gotta look cool and balanced at the end of the day.
I would also recommend sculpting over traditional poly modeling. The sculpting environment is much more immediate and artistic. Especially Dyntopo, which allows jumping into practices jams without much preparation or technicality involved.
It sure helps if you have fun along the way!
