This is a model I made a while back just for fun and practice. I sort of hit a mental roadblock with it at a certain point and just put it down with the goal of coming back to it later to finish it. Hopefully I'll have a chance to soon. The image above is a quick paint over in Photoshop to add a few details and lights. My workflow for designing it was I'd work a bit in 2D then, build that in 3D, then paint over then build in 3D, repeat, repeat.
Here you can see an earlier version
I remodeled the tires after that point, using an awesome piece of software called 3DCoat.
Also made a few other tweaks you can see below.
Hope you guys like, and as always thanks for stopping by!
