Thanks to all for the replies!
Here's my progress. It is still very rough, tried to find a way to make the bark-skin...
@fantasymaster you're right about feet, I decided to make something like goat hooves.
ohh the sculpt is looking nice! i look forward to seeing the progress!
great character, feels good. Must think on wood structures my grandpa did collect that have looking like a real face.
Great update, one of my favorites. 
Very cool indeed!!
this is coming along quite nicely, cant wait to see the progress!
Holy snap this is sick!
Looks really nice, I think the "horns" or "head trunks" need to be more pronmionent, but is only an opinion. Keep working hard!
cheers
good job! coming along nice.
cool concept, great job
oh yeah. Face looks awesome.
So brutal. Like it.
Cute conception! But one thing.... maybe fists must be a bit bigger.
Killing it for sure! love the design and the expression too!
I agree with @ololodya .. making the fists bigger will make him look more stronger and powerful ; more like a secondary weapon.
Nice update.
Woaw! Great job. The face is so perfect.
oh i like that glowing part ! and awesome proportions!!
Thanks guys!
@digitalartist what about these new horns?
@ololodya and @nevs36 about fists, I dont know about bigger, but I will make them more noticeable.
Here's little update, new horns, pose test and bow sketch.
