Placing sources in the description works fine when you have more than 10 images.
I think if you made the image more Vertical than Horizontal it would lock in your diagonal design of Castle/Jack/Cabin. Placing the Moon behind the Castle and adding a glow would give the moon more purpose instead of loitering in the dark part of the sky. (IMHO of Course) Reducing the opacity of the cloud might help let the second hand of the giant shine through as well. Good luck, and great job

The clouds are too opaque. The skin tones & light sources are different on the arms. I'd recommend just keeping the one in front and the image would be less confusing. Otherwise this is a good effort.
