I like this . Nice concept . Of course there are things that I think could be improved, but you only did 30 mins on this so I can't really critique you on the detailing part etc. I will just tell you a few little things that I think could be improved. For me I like the building, I'm not quite sure how big it is supposed to be though, I can't quite tell from the painting. As for the snow stuff further away in the picture, I'm not quite sure whats going on. (about the middle of the painting). Not sure if it's because you didn't detail due to time or something else. But it seems to just blend in which cuts some depth from the painting. As for atmosphere, I think you pretty much hit it on the head with this one . Maybe it could have a little more contrast, but I love the colours and overall atmosphere of this one .
Anyway, doing a great job as always especially for a break! Hope it helps! Keep em coming .
