Impressive. The detail in the muscles are without a doubt awesome. What caught my eye was the flow from the arching horns to the spread out arms. With all the muscles here the pose suggests the creature is eerily flexible and nimble too. Nice work.
thanks for noticing that. it was originally supposed to be more of a twist to the torso with one arm back and one more in front but i changed it cause i liked the relationship of the horns with the arms plus the character was described as using his horns to ram so i thought the pose conveyed that a little better..
