Concept drafts for vending machine

Hello,

We would like to commission 3 x concept drawings for a wall-mounted vending machine design. The engineering of this machine is entering prototype in the new year and thus would like to start working on the final look of the device. The device uses gesture control and various AI components therefore the main keywords we are considering are 'minimalist' , 'modern', and 'sleek' .

I don't want to influence creativity, so we are open to all design concepts.

We aim to run another project following the outcome of this which will take one of these concepts further to final concept artwork -> then eventually 3D CAD models.

Deliverables:
1. 3 x draft concept sketches
2. (up to 3) revisions per sketch.

Thanks
Tony
