Hi there, I'm here to bring you a bit of Critique cheer on behalf of the Community Critmas 2018 team.
I'm always amazed at what people can do with photo manipulation. It takes real skill to collect a bunch of stock images and turn them into something new and different. You've done an excellent job here, and have created an incredible Christmas display that has a lot of atmosphere and beauty (especially in the wonderous sky you created). The reindeer is a nice addition, along with the twinkling lights on the trees.
Something I feel that could be improved is to bring a bit more light to the reindeer. The tops of the trees have highlights on them from the sky, but our deer friend is in shadow. Looking at the base of the trees, the shadows are playing on the bottom left of the screen, so perhaps this could also be reflected on the reindeer. This is just a suggestion that from an audience perspective, would push this photo further than it already is.
Thanks for sharing Best wishes,Meterious (team leader of the Holly Hand Grenades)
