Nah bro it's not nitpicking I asked for people's opinions and yea I changed the blocks to slopes before because it was annoying me, I think I'm going to keep the background walls though just because I kinda like the look but that's just my opinion. I'm also gonna add an extension to it with a room of armour stands displaying every Dev set (I've got 6 so far)
You might want to make slopes for the walls outside, to fit with the pod at the surface, but at this point I'm just nitpicking...
