Oh my, this is amazing. I definitely get what you mean. The face is symmetrical and natural looking. Also, looking at the difference between the two drawings, you've improved a lot! the only thing I feel that would make this piece even better would be to add a background of the outside of a palace or something. Something to give it that little extra. I do see in your newer illustrations, you're drawing beautiful backgrounds so I guess saying it now doesn't really matter.
One more thing! I noticed this right before I sent this through. The fingers seem a little stubby. I think this is because they seem to be the same size. Maybe give them different lengths to make them seem less stubby and more realistic. This is more for the top hand. The bottom one is fine.
