I was very pleasantly surprised by how good this map actually was. For your first map, this project was by no means bad. But, unforuntely (this is a personal opinion take it with some salt) I am not a fan at all of the daytime aesthetic. I really think Quake's art style is suited more towards darker atmospheres.
Although I have made brighter maps, so I cant criticise it too much, but I think if you made the level darker and made it a night aesthetic instead it would be 10x better. Other than that, I have no criticisms. It was a bit on the easy side, though. But that's just personal preference. Will play again on Hard.
Also your brushwork, details, and texture choices are A+. Well done. Spot on. Keep making more maps!!
