I love many things about this picture, where should I start? First off the environment is very interesting and well, big as the title puts it. It's unusual and feels very mysterious and magical. The way you drew the clouds is so beautiful too! And as for the characters, I really like how they look. The linework is very clean (had to open up the image to zoom a bit haha) and the coloring and shading is also really nice on them. Just great work in general, keep it up!!

I dig how big the area feels~
