Great job on the shield. I like it all, the freehand, the NMM, and the blue/teal background.
Yeah, as long as you're driving and not flying, I think this is a great way to transport figures. I just bought some cheap tubs at the hardware store. Another option, if you feel like going fancier than the dowel, is to use a small table leg. You can often get short (6" or 8") ready made ones at home depot or a store like that. One thing to watch out for is be careful the tub doesn't tip over. I've had that happened when I've had to break suddenly. Depending on the size of the container, you might be able to wedge it behind the front seat of your car so it's not able to fall over.
Here's a pic I found on my phone from a few years ago. Got a bunch of my guys packed in and ready to go to a show!
