So, You're Going to London? (SYAC Contest)

So, You're Going to London..?
''Why, yes I am..!''

I made this for the contest (and to spend some of my free time although the deadline is really near) by Tom Preston:

Honestly, I can't really think any reasons behind of this drawing...It's all totally random..If some of you will ask some questions like..:
-why Andy's driving 3 wheeled car like the one you see in Mr Bean Tv show
-why Alex is on the top of the car
-why Carl is on a bike
..or anything, that..I can't really give valid reasons..
Maybe because they are in...London? ..d:

So, I just hope you like and enjoy it...
