Hee Hee, just like the living plastic one in Doctor Who!

Very good but take away the rubber part of the tires and then it will be perfect

I've seen the name Optimus Prime somewhere just like yours, I am suspicious on how identical the names are. hmmm... Anyways, your waste container is very accurate for its size. The lid and the wheels are great, but the rounded front edges are the best in my opinion.

Great job, but is it to minifig scale?

This MOC is absolute rubbish...in a good way.
