Help making a diagram

[PowerBookG4]

Hello everybody, I have a request from anybody with time who happens to be bored and wants to help me out. I am making a video for my girlfriend so that she is not as nervous when she takes the driving test on her 17th birthday, lol.. as good as i am in final cut pro, I tend to not be good at all in photoshop and wanted to make a good looking digram of the actual course with like text and stuff over it (its more of a joke video then an instructional video.. i intend on making it really funny) so I would like ot know if somebody could make a diagram of the course that looks like a road and grass and what have you.. kind cartoon-ish i guess.. the couse lay out is the attached image I tried as you can tell I was very much un-successfull, lol.. thanks in advanced to anybody who attempts this I will owe you a favor.
