Picture combo needed

[mapequipment]

Hey guys I have a favor to ask, this is a little odd because I'm not needing a cut file just a few pictures pieced together. I do okay with cam and light cad stuff but not really familiar with the software to do this. I'm on a motorcycle race team called the Jackwagons, and somehow I got voted most creative and told to design some shirts. Here are the pics I came up with but not sure how to combine them. What I need is the mule to be pulling the wagon, hauling trophies, doesn't have to be this exact wagon or trophy but prefer to keep the mule if possible. Can any of you guys help me to combine them, don't need a dxf just a image to send to a shirt printer. Any help would be appreciated, thanks in advance guys.
