Normally I'm the guy that tries to be a bit more positive about things I think, but I'm just not all that impressed..
It's looks good, don't get me wrong, but it looks too simple. Apart from a few of the smaller things like the tombs, it's not too detailed or creative imo. It's very simple
The colors are also a bit bland. I know it's difficult to make a diverse range of colors when it's all supposed to be made of sand and brick, but still.
Since it's just a WIP I assume it'll be better as time goes on, but for now it definitely still needs work in my opinion
