I never thought I'd need to look up youtube videos on how to pull a pint, but here I am :P. (I couldn't find any reference of behind the bar!)
I put a tiny sequence of Rosemary and Terri in there, because I'm terribly self indulgent ;).
Also, you can see I copied the placement and angles of the crowd loosely, and then worked from that! I generally like to learn things from scratch, but comics often require shortcuts ;).
I tried to have two compositional elements consistent- a curve at the top of the crowds, and a curve at the bottom, hopefully it adds to the flow a bit!
