I feel like taking a crack at critiquing this, since I have zero knowledge about Game of Thrones. I'm going to start by guessing what each one is, moving top to bottom, left to right:
Stag, wolf, squid, bear, sea serpent, jelly fish/squid/octopus, fleur de lis, bear, and some kind of plant.
Some of these designs are hard for a non-fan to distinguish because they appear to have swirled or drifted. I'm not exactly positive of the purpose of these latte decorations, but I think, apart from being a sort of timed art, the main idea is that you can distinguish clearly what is being represented.
As a nine-part piece, I believe that the total composition could have been put together better. Most of the colors of the beverages are earthy, but then you have the orange, the blue and the vibrant green, which stop my eye. The orange in particular is very distracting.
All over, good job. I hope this was a lot of fun and you should keep doing what you do, especially if you like it.
