Another nice piece of work!! I think you should able to find yourself a job in no time. Do you want to try US? There are a lot more opportunity here
I kind of agree with LoGao, your overall pose and timing is very nice, the body mechanic feel very natural. The only tiny problem is too much motion, especially toward the end when the dragon shake it's head. I understand you try to put more subtle movement here, and I can almost see you take reference from an eagle or other bird like creature. But remember a dragon is a giant creature with a lot of weight, if you can tune down the motion of the wing toward the end, it will show a bit more weight as well as a stronger key pose. Again, this is already an excellent piece, I'm just trying to be picky here.
Good job!! Please share more of your work!!
