Thanks all for your reply,
I agree with NickZ, I will remake the back 'cause i’ve drawn it randomly
(thanks for the tips) and will refine the biceps too. I knew that something’s wrong about the arms but I don’t know what… thanks again. For the hair,
I will retouch it once I will fix all volume of the entire body.
benhobden: I use mostly the clay brush, and sometimes the Dam_Standard brush for streaks.
Update coming soon.
I like the way you did it great job
update with the back entirely resculpted, decrease a bit the volume of the biceps and made some details of the hand.
Very nice work! 
Now give him some legs! :lol:
Great update. I think your changes have improved the model nicely. Im looking forward to seeing this completed. 
Nice improvements, well done. It would appear that seeking and receiving critique is a very valuable process. Huh, who woulda thought?
Hi all,
litle update of the legs and modeled some armor.
Looking pretty good, I would say your overall scales seem to work pretty well. I think the knees need to be reworked, and the cloth pieces in front and back need to be reworked as well. Right now thos wrinkles arent really flowing to well and I think you have too many of them. For stuff like that its relatively easy to get reference. Simply hang some cloth you have in your home in a similar way. Pretty good update though overal
