Thank you!
I’ve uploaded the topic with some other images as well.
I think is possible by only using Blender’s sculp tools.
Those stylized characters don’t need much “high frequency” detailing done in sculpting, you can use textures, I really recommend you start with characters like this.
YanSculpts YouTube channel is great, I recommend you check his videos.
I don’t have a channel yet, but I’ll be uploading some stuff soon.
