Door flap fun painting

Just loved this class, it was so different, my inner child and imagination were truly enthused! I was looking to make a magical winter scene as winter is really coming in now for me. I painted the door in metallics and used salt for a crisp icy feel but it’s fallen a bit flat. I think the outdoor scene needs more colour. would really appreciate any suggestions on how to lift this idea!
I will try this again for sure. I haven’t stuck them together so I can try a number of scenes until I’m happy.
