I like the storage looks really good.
My Suggestions
1.On the storage units, try adding one of those storage unit locks on the garage part. As you can see on most of them they have! locks on the doors.
2.I would probably remove those poles. That are by the garage part and add different, colors to the storage part: for example like make the garage part blue. And add a more brighter white color to the storage part.
3.If you want to add poles to your storage, i would suggest you make them! a little small instead of having them big and tall. By the garage part here is a, example of what i mean!!
