I need an architecture sketch

I need an architecture sketch regarding a 50m2 store. The sketch need to be done in autodesk sketch. It involes the geomentry of the store and a sketch of a counter. No details needed, meaning ceiling etc.

This is the first draft sketch and we will continue further more with a series of 3-4 sketches.

At this point i just need a sketch depicting the 50m2 cell and the design of the interior counter in 2 variations

I attach 2 different sketch images to understand the style.
