That looks nice for your first map, but as far as playability goes, this is pretty bad. There is virtually no cover, which is no doubt emphasized by spawning with a sniper right in front to you(speaking of which, did you make it so you have to nade jump to get to the sniper?
There also seems to be a serious lack of weapons on the map. Sniper and missile pod at base, a shotgun in the middle, an ar on the hill, and a plasma pistol and magnum in the tunnel. Maybe there are more, but as far as I can tell it's very barren.
Also, while no doubt aesthetically pleasing, having a giant tunnel does not lead to good game-play. One room with one entrance and one exit sucks, and it takes away the ability to jump and strafe.
I see no reason to put fusion coils right next to the shotgun. You are either going to shoot them before you get there, or they will be shot before you get there.
Also, the forging itself is very minimalistic. Bases made out of 16 pieces, a one way tunnel, and more of the same for the other structures.
The center structure looks nice, but that is about all the aesthetic thought that seems to have been put into it. The sniper spawn looks lazy and just thrown together, as do the bases too really.
The turrets are either ridiculousness overpowered with complete control over the map, or blocked by the tunnel, I cant tell which.
There is also little to no risk versus reward put into this map. The shotgun, one of the most useless weapons on a map like this, is put in the center with no cover, while the AR, another useless weapon is on top of a hill making you even bigger sniper bait. To contrast that, you spawn with the 2 most powerful weapons on the map right next to you. Also, with only a PP, magnum and regen, there is really no reason to go into the tunnel.
To end, I want to say that I'm not bashing you. You are very inexperienced, and it shows. However, ignorance is no indication of a lack of skill. I would recommend that you first go over to
forging 101 and learn the basics of forging, and also take a look at
some of the more celebrated maps, and learn what hey did that made there maps great. The main thing to take out of these maps is their effective weapon placement, the correct amount of cover, risk versus reward, line of sight, as well as map flow.
Also, I haven't DL'd, so I don't know how well you placed your spawns, but, as much as I hate to say it, you probably need help with them too as they are some of the trickiest parts of forging. You can find an excellent guide to spawns in forging 101.
EDIT: Wow, I really am a wordy bastard. Sorry, but I hope it helps.
