So Im looking to get my van wrapped up for my plastering business located in the Netherlands. I have been working on this design lately. The business name translates to: Plaster Corner. The business name AND products already imply for a design with squar (plastered)wall like shapes. So for the sides i made a square like shape in white space, so my logo can be placed in full color. Which im pretty happy about. For the backside im trying to get the following hierarchy, Attracting interest -> contact details ->logo. Im having a hard time on the backside of the van which feels a little cheap for now.

I could use a opinion outside of my (supportive) friends and family. Am i going in the right direction or do i miss out with this design as a whole.
