To be honest, I didn't download it (my disk space on this laptop is dwindling), but I did investigate the screenshots
I also did not play the original "Thunderstruck" by Firestarter, so I have no precedence going into what I'm about to say; feel free to ignore this...
The map looks like the
start of something it would seem. There is plenty that could be added, based on the screens. If you had fun making it and playing it, then good stuff. If you wanna make it a cool place to play around in, frag people in, and make them believe this place could really exist in some alternate universe, then it has a little ways to go. I may not have precedence on this map's history, but the precedence on the history of level design does have something on this map. But this map has nothing to show for that history. So, with that, I urge you to seriously consider what all may be possible with this concept and perhaps look into what might be holding this map back. A few places you could look into (based solely on my opinion) would be the lighting, architecture, and setting. by setting I mean, there is nothing there (in those pictures) to tell you where you are in the world (alternate universe). What's going on? Why are these FF guys fighting there? -Add some props at least. Some decals to show if this place is worn-down or not. Or maybe a 3d skybox to give some depth to the space surrounding this map, especially if it just a box.
The architecture is a start, but cannot stand on its own. Add some detail props to give it some context. Or model the brush architecture based on something well-known or pre-existing. I'm guessing this is in the desert somewhere? This map needs atmosphere above all else. Simply put: add more detail in textures, brush geometry, and models (don't forget sounds!).
It's a start!
