Looks great! But to make it better in my opinion is to add some colors and a background. It would be nice if your dirt starts brown and as it goes down becomes blue-ish. Also above your platform you only have green, add more colors, red, yellow, brown(like a tree or a dirt tile or some colorful flowers). Also if you have a background with more things in it :p like mountains or a forest, i am 100% sure that your pictures will get much more beautiful!
