would you mind to post a link of the original piece to see how it looks like and based on that what could be improved?

Great work B! I love the blue light on the right end of the canvas. I think if you accentuated that light source a little more, perhaps having it reflect on the trees, that would create a great effect. Other than that, I might recommend trying to tighten up your rendering just a little bit, that way the forms are more readable. Other than that, great job.
