The base layout of this map is awesome but IT could definitely use some tweaking. In its current state, there are a few paths that are either a. redundant or b. reduce the significance of other paths. I would suggest slimming the map around the edges especially by T spawn.
I very much believe in a design philosophy of having the entire map be viable in regular play, as apposed to having dead starts (maps like Nuke or even Inferno). That being said your map seems to embody this and I would play to that. Perhaps you could remove the outward paths by t spawn and re-angle the above ones to allow for players to rotate through T spawn, but not encourage they stay there too long.
I would argue that the layout isn't particularly complicated as it is, but rather clustered with a great deal of redundant player splitting areas. Running around in game is rather overwhelming as a result of this. Some areas have far to many corners to check and should be simplified. I'd love to see where this map ends up though, you're off to an amazing start.
