*The Sock Hop Diner*

I painted this work for several days … and, it seems, I again surpassed my possibilities  

By the way, this is a full-fledged work to order, when was the last time I took this for? I already don’t remember 

In any case, I’m happy with the result and the customer, too   

“The Sock Hop Diner of Ponyville. Home to a team of professional Rollergirl waitresses trained in speedy service with a twist. This pretty lady is the leader of the pack. The Sock Hop’s lead roller girl. She’s grumpy today. Had to fill in for somepony at the counter instead of working the floor with the other girls. Oh what a day!”
