As okidoki mentioned above, we have a wiki with tons of curated resources. We even have example character meshes! http://wiki.polycount.com/wiki/BaseMesh And tons of example wireframes to examine and learn from http://wiki.polycount.com/wiki/BodyTopology http://wiki.polycount.com/wiki/Limb_Topology
Well at least it's a reasonable start! Also by the way was it modeled off of a background reference image or concept art? I’ll recommend finishing translating each individual blocked piece, into a high resolution (sub divided high poly) artifact free base mesh which in my opinion believe is the actual core…
