Hey, I like that you post improvements on the map, but there is 2 quick things that i dont quite like.
As a first you start with using non 1.8/1.9 blocks such as for example Campfires or magma blocks (just to list these 2 i saw)
My main problem though is that this map looks really blocky thought, if the theme is "blocks" ofc thats ok. But what usually is the reason i would build a map is to make it look as non blocky as possible. (this is just for me though)
If I explained it wrong, feel free to ask me :)
