Shedditors, what would you add or fix on my shed?

My first shed, a kit from the local hardware store.

The rise for a ramp would be 18" high. I'm unsure about paint colors. The main house is brick and white siding on the dormer, white window frames. I did purchase a Gfloor mat in black to cover the floor but I plan on using a floor paint first for added protection. I'm a newbie and welcome feedback and ideas.
