landscape studies

Looking back at my earlier art I'm seeing that I've lost my interest in polishing my work. I feel that I have learned more, but lack the motivation to apply or practice it. Even with these I stayed very rough  even tho I intended to try to render them more realistically. I need to get in a habit of polishing them more or find a way to make my rough strokes more aesthetically pleasing so it looks like it was intentional rather than I'm just too lazy to finish. All boils down to practicing more. So here are some of my attempts.
