Hi there,
It will take a bit of time to do, but doable. The feel illustrations to be on the correct perspective, otherwise it won't look professional. To accomplish this, I need to draw the vehicles in the same "plane" as the truck in the foreground (I hope that makes sense). For instance if the vehicles are in different planes where you see the hood of one as if standing on a higher plane and another vehicle looks like it's being seen from a lower level, then side-by-side they will look like clipart randomly pasted next to each other.
What I can do is shift the bed so that the other vehicles show a bit more profile Same cab as now but sharper turn of the bed like

Another option would be to just have two vehicles on a truck trailer (no cab showing). Still giving emphasis on the business as a transporter and not a dealership of fleet vehicles.
I had used the Celina Lighthouse but that is a very easy change and can be done in a heartbeat.
Lastly, I don't know which version you would like to see. I had not realized this was a lower prized contest, but I'm already vested (besides, I don't mind drawing vehicles) however, I want to at least be sure that I work on the correct version. : )
Cheers!
