This coloring page is so much fun! The girl and boy look like they're having a great time sledding down the hill. Both of them are wearing brightly colored coats, with the girl in purple and the boy in green. Topping off their look, they both wear bright red hats. I'd suggest coloring the coats and hats with bright, vibrant colors to give them an extra pop of cheeriness! The snowy hill surrounding them could be done in varying shades of white and blue, and perhaps some additional colors to make the scene more interesting. This could be a great coloring page to get creative with and add extra details, such as snowflakes and trees.
