I would use the actual critique feature, but I have no negative points to make so that'd be useless.



The color is great, the sense of scale is grand, the lighting is nice, and it's just plain beautiful.



You could possibly improve by having a few less clouds, and adding more detail, but honestly it's all part of the painterly style you're using here and it's fine as is.

Unless you were going for hyper realism, in which case, those are actual mistakes that you should fix, but I think it's pretty clear you wanted it to look like a legit painting instead of a photo.
