Nice, a fun looking MOC, which I was a LEGO guy and could race some of my cars on it! - Oh wait, my 8 wides are as wide as the whole track, guess you can't pass me now! Nice work, looks really good especially for a kid.
Man, that reminds me of the good old times (hey, I'm 22 ... I shouldn't talk like that ;p ).
It's a nice creation and I really like the way these pictures look like.
Quite like you sit in the living room, surrounded by your grandchildren, pointing at pictures in a photo-album saying:"Look, this was what I built when I was your age."
