Don't know what it is about Hinata in orange, but it works.
Getting straight to the point though, great work on the design of the outfit. It's different enough, but it still creates a very fitting look for the usually-modest Hinata. You also did a solid job coloring this, giving a nice share of attention to even the smaller details, such as the buttons and the soft blushes on the cheeks. The hand pose with the larger Hinata also creates a very nice gesture.
Glad you decided to color this. It's well done, really.
