If i were doing this i would follow the reference image (its a good one by the look of it), i dont really get that many good ref picsā¦ so i would make use of it.
there apear to be a few tris, i would also try to remove them too, they make it more difficult to add extra detail later (+animation etc if you are doing that).
Hope it helps
Edit:
i mean for the leg (the rest looks to the reference)
hi, i donāt plan on using catmul subsurf since it isnāt very good with sharp edges, and since I need some sharp edges (particularly in the head), im using just refined tesselation and simple subsurf.
If you notice in the reference picture the legs are a slightly but tiny in comparison with the body, whereas in my model the legs are hugely larger than they should be (like when you concentrate on drawing part of something and becomes out of comparison).
However at the moment vertex pushing looks like my best option
You can easaly achieve sharp edges with the catmull-clark sub surf by selecting the edges you want to make sharp and then pressing āShift+Eā and then moving the mouse to adjust the amount of sharpnes desiredā¦
