Meditation

For the vision, I can definitely see yours! While I agree that it's great practice to begin working on more complex poses, and you've definitely done that.

I can't give a stellar rating on originality, as it is your rendition of another style. Your technique is improving however! I most certainly admire your wanting to try more challenging artwork to improve. A suggestion is to maybe erase some excess lines, as they can be confusing and weaken the overall picture.

However, keeping in mind that it is only a sketch, you're doing really well for a work in progress! Keep doing your best~!
