This is a lovely painting and i think you're already doing a great job, what i mainly notice myself and i find is pretty important is working with darker values and emphasizing shadows more! this will make the image feel like it has even more depth and be easier to read/view for the viewer as well. i roughly added some shadows sporadically just to show how much it can really add to the image, i especially focused on shadows on the building adding a stronger composition and helping the viewer focus on the scenery and what's Infront rather than the building competing with the rest of the image, especially the roof! it acts as a vignette feeling that helps making the viewer focus more centrally on the image, and makes it more enjoyable to look around. | Artwod Feedback
