Nice greens. Your texturing is decent but I would recommend only use 2-4 shades of green per tree or patch of grass. You can use a different 2-4 shades for a different leafy object, but I've noticed real-life trees and grass have distinct light and dark areas with no need for much in between. https://cookingintongues.files.wordpress.com/2014/02/balestrand-2-2.jpg
