Dean/Dominic/Luna
Slightly disappointed, Dominic nodded. "I'd appreciate that, actually. Like I said, I'm not the biggest fan of book-learning, so if we can narrow the amount of books I have to read to appease my curiosity, I'm all for it." He watched both Dean and Luna carefully as they cast the animation spell, smiling at the antics of their animated figures. "It's a bird! It's just... far away." He grinned and then attempted the spell himself - to no result.
It took him a few more minutes to work out what he was doing wrong (wand movement, as usual) and get his own drawing to give a few apathetic flaps of it's 'wings'. He shook his head, annoyed at himself for not getting it but knowing that now was not an appropriate time to stand her and make repeated attempts. This wasn't his workshop and he was supposed to be helping everyone else have fun, not drawing into his own world of problem-solving. He summoned a few of the left-over colouring pencils and started carefully adding a strip of green 'grass' under Luna's dancing girl. "Maybe I'll provide the backgrounds and you two can add the action," he suggested.
With a glance at Dean, he walked around and sketched in a 'beanstalk' on Dean's other side, with some white-blue clouds at the top.
