With a bit of work on the head sculpt but I will have to find a way to blend this with the dynamesh base that I will be dividing up before working more on it.
Thanks a lot for commenting The problem is that it's a dynamesh with +1000 resolution, and if I reduce the resolution, somehow I will lose the form. Is there any solution for this case?
Good practice! It looks like the same bust model is used for these studies. I would recommend dynameshing it to get rid of the biased topology. Keep it up!
