Sorry, but it's ugly, boring and basic, with not very much effort put in. I'm sure that once you do start dedicating more time to your mods, they will become much better, but you can't judge something that's not there.
And the people saying things like "How about you try mapping before hating on someone else"... I have made a map before, which I think was okay but fairly small. Also it only worked for me because I did something stupid which I don't remember.
I love it because IT IS JUST ENOUGH TO WHERE MY COMPUTER CAN RUN IT WITHOUT HAVING MILLIONS OF ERRORS AND CRASH! keep making maps lowest graphics for bad computers and while you are at it so people don't criticize you for effort put this in the description...
< NOTE! : this is supposed to be for bad computers w/ bad performance >
The textures need work, there are clipping issues all over the place, road is chunky, camera issues, tunnel is quite big in terms of realism, I appreciate that you are making mods, but don't let this stop you from making maps, it's better (at least in my opinion) to put out a well thought out map that isn't rushed and has been smoothed out, it's best to put out a good map mod that will give you experience in making a higher quality mod instead of making multiple lower quality mods.
