This is my Tiny Turbo 4-wide Freightliner FL-86 in G1 Optimus Prime colours. I've wanted to have a go at this for a while but all previous attempts just didn't have the right feel for the scale.
About this creation
Here's a side view with square front lights in stead of round. I'm not sure which looks better.
On my first version, the front grill protruded out of the front by the whole tile so I had to find a way to recess it whilst maintaining the upside-down front bumper.
Here's a shot that shows how I achieved it. It's a simple solution but only became possible with a piece I got with 60007 yesterday. Even better though is how it sticks out just a little, giving the facia some relief.
