Hey, practice is good too.
The best one I've ever found is the MakeHuman mesh, but the full mesh is much too high-poly, the medium mesh has some bad deforming problems (it needs more edge loops but I don't think it's been updated in ages), and the low-poly mesh is much
too simplified. Nevermind that the UVs are a nightmare if you plan on doing clothing by pulling out vertices and painting it.
Though checking OGA again (as I haven't in a while),
this one seems decent (and is CC0), though neither it nor the female one is rigged, so I'd need to find the patience to do that.
