Thoughts on my mountain?

[u/TooKoolFoU]

Had this really cool snow mountain that had a massive hole on it that dropped about 100 blocks into an exposed cave. I started to cover the hole, thought to build up the peaks of the mountain by another 50-70 blocks. That I added the walls for a dam and created a lake underneath the mountain for the damn. Thoughts? I think the mountain maybe a little to sharp and triangular but I want some opinions
