This level is not too hard to beat, it isn't meant to be. I made it more for the fun of creating another level than making a 'masterpiece'." I certainly wouldn't call it an easy map though, and the start should keep you quite busy. Themes include bricks and stone, together with some battles in confined spaces. And if he didn't intend it to be a masterpiece, why did he include a big crate room? The final battle isn't what it seems, but once you have worked out what is what, you have a big ammo surplus (and an invul) to wipe out the resistance.
