HI, im new here but i’ve been working with blender for at least 5 years, specially into character creation, i put a lot of effort into the anatomy of my characters but allways trying to get a clean topology for the rigging and texturing, uv mapping, blah blah blah, i’ve decided to challenge myself doing a full retopology of a sculpted model, i ususally dont work with this level of detail but there’s allways a begining for everything. 
At first it was hard but manageable, but right now im drowning in doubts about how im gonna do x part or y. 
here is some image examples of how the model is going^^:
