I build lots of little hills but this is my first time building something that looks like a mountain. I added some custom trees, 2 little lakes and lots of flowers. Thank you @Heatdude Da Waffle for teaching me how to make custom trees!
this looks pretty good for a first! I will suggest to remove a bunch of flowers, splash some bone meal, and give the stone a texture. add some leaves coming down from the top and add some stone slabs, stairs, and walls. to the trees you can add some fence, slabs, stairs and some custom heads to give it a better look. hope you can learn from ^ :)
Thank you for the suggestion, I will remove flowers but I don't think fences, slabs, and stairs look good on trees.
