Wanted to show some work, made with a few hours here and there.
Not finished by far, but hope to be done with the modelling next week.
and ad some pouches, a kristal on his staff and so on.
But haven’t put it up anywhere to get some constructive critisism, so here goes 
Hope you like it, if not give me some pointers.

got some good basic form. I might suggest increasing the hunch on him more…

And I always heard that trolls were gnarled and twisted, you might want to increase other physical deformities as well. Maybe make the length of limbs uneven is proportion and maybe a little more some idea like neurofibromatosis. (not to make fun of such people, but for an example… could have been where the troll legends got their start anyways…)
theres some lovely detailing on the face here and a great knowledge of muscles and form, i’d like to see this in a pose or something (as well as the deformities mention in the last post)… the head seems a little out of proportion, or at a strange angle or something. so a pose, or just moving the position of the head might change the overall feeling and make it a little more trollish
