So I finished the retopology, but when I compared my retopology with other YouTubers and other 3D artists, I find that my retopology is flawed with a lot extraneous edge loops. Furthermore, I learned that the approach to retopology for 3D animation is different. I was interested in 3D art because I was interested in making 3D figurines. But after doing some more digging on retopology and 3D animation, now I'm thinking about doing some 3D animation, which means I might have to redo the retopology to make it optimized for 3D animation.
So I feel like I'm at a crossroads on where to go with 3D art at the moment since I'm more used to creating 2D art, and there are A LOT of tools and features on Blender.
Here is my original sculpt along with my retopologized 3D art.
