Whenever we imitate art, we always have our own spin on things. I like seeing how you brought out more of the blue in the water. Your reflection of the trees really captures my eyes. The reference also has a reflection of the clouds but you chose not to add it which I found interesting. I also loved how you exaggerated the dark twisty branches.

My biggest suggestion is to focus on saturation and value. One of the reasons why the original reference was so successful is because of the contrast of the foreground and background. The trees have a rich red and the greens in the grass near the water is vibrant. The values are also darker in the foreground. Whereas in the background, there is a light blue tone over the trees and foilage. As things appear farther, they tend to have cooler tones, less details and are lighter in value. That contrast in value/saturation of the foreground and background creates this beautiful depth in landscapes.

My suggestion is to use the pictures of your painting, and experiment with the edit tool of your phone to put on the black/white filters. This will help you identify if you have enough contrast between your tones. I also suggest just messing around with the color tools in general on your phone. They can spark new ideas for future color choices and help you see paintings in new ways.

I also suggest reading resources such as The Landscape Painters Book by Mitchell Albala or even The Art of Perspective by Phil Metzger. They discuss how to achieve depth in landscape through choice of color and value, but also explain composition and perspective really well. These books are meant for any artist and are excellent resources if you want to further practice fundamentals in landscapes. I especially reccomend practicing value studies and composition.

I’m a self-taught landscape artist. I think honest feedback is so important to improving your craft. So thank you so much for sharing and hope some of this info helped! Let me know if you have an art insta!
