I've never tried to make anything this big before, so there is a LOT of first try stuff here: the ocean, sky, beach etc are all airbrushed which I have no clue how to do, so I can't really tell if it turned out right. It probably all looks OK individually, but I'm not sure how good the picture looks... as a unit. You be the judge.
Oh, and Pinkie's hair. It's wet so I had two options - give her the totally straight hair a la Pinkamena, or retain the curly element of her mane. I chose the latter.
I got the idea to do something summer themed from this group contest: [link]
Edit: Contest is now over, grats to all of the winners! Even though I didn't win I was still glad to participate and make something so far out of my comfort zone.
