These are Dave Roman and Raina Telgemeier. They are involved is so many projects, I can't list them all, but their latest is Comics Bakery!
They are the nicest, cutest, most talented couple I met at the UK Thing, it's a shame Carly wasn't there with Chris Hastings because then they could have battled for the cutest couple prize... TO THE DEATH! XD
Unless somebody requests it, I won't make any make any more pixel portraits of the people I met and I'll try to wrap it up tomorrow! :3
