always release a beta version first. That way if you need to make any changes there wont be any 'map version differs' problems, and even if you think no changes are necessary its still good practice. Just append your mapname with _b1 or _beta1 or something similar.
I think your ladders look great, but you should avoid overlapping brushes as it can adversely affect the tris (not something you want to do in bigger maps). In this map you can get away with it, but its good practice to avoid overlaps where possible.
Some of the face textures on you 'haybails' are not aligned properly. Select the face and press s, then enter a value in the r box and press apply to face to rotate the texture.
This is not so bad, as leaving one unit gaps can help to reduce r_speeds, but in the case of this map i think you can afford to move the ladders right back so that they're touching.
At the moment you've got an info_player_start entity outside the level with lighting as well! No, no, no, no, no my dear boy! Box that room up like below and you'll cut your compile time in half.
Other than that the map is not too bad, although theres not much to it. I don't think you should have this map as a gunning map, its waaaaaaay too small. Also, it is not immediately apparent that the poles that lead up to the platforms are ladders, I'm not sure if i like this. The barrels are kind of weird too, not wrong, just not to my preference. Some of the metal textures could be realigned to make them neater, but thats up to you.
I think the map should give you a good idea of how to manipulate brushes and deal with entities, but i don't think it should be released. You need to take what you've learnt from this map and apply it to a more ambitious venture.
