Looks fine the way that it is. The space is limited so there is not really much that you CAN do besides paint the door a fun color.

You could add a nice cushion on top of the bench in a fabric that coordinates with the rest of your decor. I think what you have done is functional and uncluttered looking which is difficult because of the small area you have to work with.

Consider a wider area rug, measure from the corner over to the bench. I'm picturing 2 adults, 2 kids & 2 dogs coming in and trying to stand on a tiny island...
