for me it's been a never ending process of tweaks, but two hours for a from-scratch base is pretty quick. shapekeys can take awhile but since you can combine them, it gets faster and faster as you go. starting out high poly is a good practice. it's easy enough to decimate later. I aim for 30-40k poly base + head and save the rest for clothes but if you are just going to cut shapes out under clothes anyway you can leave it high poly.
