Hi, so I made the dustbin without wheels (doesn't really matter that much). There is a image in the zip file with a height map and a UV map, I took the pic that Power provided and made a front and side view to use in the model. It was a little tricky to remove everything like the sidearm, wheels etc. There is also a FBX file of the dustbin if you want to use it or for future users who wants to tackle this recreation.
I didn't make wheel or recreated the scene because the contest is over and plus it takes a day or two out of my schedule. I tried to make the dustbin old by deforming it a bit, you can see it on the lid of the garbage collector.
