That looks pretty good!Followed the concept pretty nicely. I would probably take a look at the ears some more, and adjust the shape and that sharp line along the ear to smooth it out some. Cant wait to see it coloured!
Cool work man, looking good. You could do a few things to bring it closer to concept.- On the concept itself the jaw/muzzle of the head is pulled a little further forward. - The hair shapes you have on the beard look cool but generally the gaps inbetween are a bit lumpy, you could have sharper transitions between shapes like the concept if you sculpted each 'hair chunk' as separate subtools.- The base of the hair bun and ponytail itself could be given more volume/length to match the concept. Also you could round out the skull shape a little more instead of having it that angular. - Lastly the hair braid itself in the concept is a lot smaller, like a third of the size you've sculpted, you could size that down to make it a little more stylized.Looks sweet though, can't wait to see it come together!
