The best words to describe those screenshots would be "Total Disaster" indeed. Not impressive at all.
The first screenshot is just a standard FPSC uzi floating around, which everyone has seen billions of times. The second one makes no sense, it has no roof on the corridor, you can see the rest of the level and segments and it looks just like crap. (also notice the very poor framerate)
I'd suggest you to read the FPSC's manual before starting gamemaking. You are clearly a beginner; but you need practise before attempting to make games. Make some levels, learn FPSC's features, don't rush and make a bad, bad, bad game. If you don't, you'll just end up being flamed to **** in these forums. It's starting to become a way of nature here.
