pretty excellent maps indeed. i think your only problems are: first map: this map as you know is pretty cramped, and although your quite the architect, its very detailed to the point where its disorienting. plus, some flow issues in this map. Second map: your second map is overall great, the only small issues with it are that your texturing is a little weird in some places, though im not the best at texturing myself, so this is a small complaint.

but hey, no maps is flawless. so other than that your maps are good, both in look and gameplay.
