I just finished reviewing the details and... I'm not sure I can make it happen. It looks super fun and is a great opportunity, but I am absolute crap at drawing trains/cars/vehicles (like, jarringly crap at them).
I wonder if it has to be of a literal train, or if we can get away with an alternative take on the word "train." Ex: train animals, train of animals like a caravan, wedding dress train, etc.
The deadline looks generous for getting it done, but I dunno...
Props to anyone who submits. Send your links and I'd be happy to read 'em.
