This is beautiful, the shading is in the correct places and there are no messy lines, its all neat and organized.
Even though you put a lot of characters you never got lazy and just scribbled and I love that!
I like how the anatomy on them is perfect and actually goes with bone structure. The eyes shine and have emotion in them, and I love the colors.
The background is breathtaking with all the detail you put into it and the expressions on their faces truly tell what they are feeling.
Overall, this is a very successful work of art.
