What The Photographer Did Right
I love the overall theme, the trees being placed symmetrically as far as the eye can reach, beautiful. The colours are fantastic, bright and vibrant but yet natural, great job on that one! The focus and exposure are also spot on, excellent!
Where Improvements Could Be Made
Personally, I don’t really mind the composition you have here but I think a better idea would have been to photograph them while standing directly in the middle as as to make the line of trees seem infinite. A good approach to doing this is to place your camera lower to the ground and capturing the trees from a really low perspective. This could make your photo seem more planned rather than a potentially random picture you took while walking around. Another option would be to shoot under the tree looking up, you can even place your camera on a tree branch to make it even better. Check out the example here.
