I then started designing the building background.

This background looks ok, however I would say it is the weakest of all my backgrounds I was unsure of how to add more detail to 2D styled buildings without using gradients or making the buildings 3D.

The final background I did was the image of carrots in a box like he was in a supermarket.
I think this background is very different and quirky and I really like the different heights of the carrots and there are some thick chunky carrots and some thin smaller ones.
