I did a lot of initial sketches of them actually up at the food truck ordering/picking up their food, but, let's just say I couldn't really get the truck to turn out very well. So instead I drew then already sitting down or getting ready to sit down and enjoying their tacos. Just pretend that the truck is somewhere off screen >_>
I hope that you like it anyway (even without the actual truck)! Actually attempting a full background for once I think was a good experience for me and this was pretty fun to color as well.
I hope you enjoy it :)
