I can totally relate. My 2 year old has close to 200 little hot wheels cars and They are EVERYWHERE. I pulled 2 out of the dryer yesterday. This is a great depiction of childhood. I have the feeling someone is going to comment on how they are "unorganized" or how it's "just a pile of cars". I think you did it PERFECTLY. I wouldn't change a thing. Childhood isn't about organized lines of cars or toys, it's about piles and messes. Great job and good luck in the challenge.
The jumbled heap of colours and shapes makes this an interesting abstract visually, while the subject matter also feels familiar and holds memories. 7, Kavey
Good colours and concept. There's a dark patch towards the left that makes it seem a little unbalanced for me. Perhaps if you'd turned that yellow car the other way up... 7 - floyd
