this is absolutely amazing!!!!!!!! you say contructive criticism welcomed? if i was to try to pick out something you could improve on, a process that would be extremely grueling and hard work, i would say that the moon isn't a perfect circle, but hey, you tell me to do that and i would buckle at the knees. amazing work!!!!!!!!!!!
ooooh! this is so beautiful! I love how you have the black of the trees then quite a colourful mountain in the background, and also how the mountain contrasts really well with the colder blue foreground
