if there´s anything really wrong about the loops feel free to shoot at me
It looks pretty good to me. But I recommend testing it before you spend a week rigging, you can do it in two ways.
- You should take the base mesh into Zbrush or Mudbox and paint away on it like crazy for an hour or so, see if it behaves smoothly and expectedly all over.
- You should do a quick test rig and bend all the important large joints, the ones that bend a lot, and see if there are any topology problems that jump out already at this stage.
This can save you lots of heartache later.
