I'm here on behalf of because your piece was in the group's critique requested folder.
I like how you have the dragon in a dark light to show hesitancy or maybe curiosity when he saw the girl. And just beyond that, you could see the ocean, which adds beauty to this piece.
The trees and it's roots adds mystery and age and you get this feeling and you'd wonder 'how long has this dragon been here?' And that bridge you drew there like the girl just crossed uncharted waters.
Overall, I'd say you have done a great job. Your lighting is good, your use of shade is good. Great job!
