Sadly, there's not a drop of artistic talent to be shared between @goffmog and I. But that's okay. 'Breathing Space' is a card game, and as such, we're trying to get away with making use of limited animations and free vector art. On the programming front, it looks like @goffmog's succeeded in developing the beginning of a card-flipping animation engine and is now refining his efforts.
Meanwhile, I wrote doggos:

1)Enamoured of naps, silk blouses, and other dogs’ chew-toys, Ronaldo is the consummate canine hedonist. His only flaw? Acute flatulence.
2)Deeply philosophical even for a dog, Sadie is haunted by impossible conundrums: what precisely defines a ‘good girl’ and how can one know when they’ve achieved such an exalted status?
3)Bella is the perfect example of what every space dog should be: courageous, even-tempered, and clever enough to play four-dimensional games of fetch.
4)Despite the name, Bull is not a very big dog. In fact, he is a very, very small dog, so small, in fact, that he is occasionally mistaken for the resident chinchilla.
5)Born to terrestrial parents, Luna never quite developed a knack for living in space. Instead of pirouetting elegantly through the air, she dogpaddles through the zero-gravity parks.
6)Brutus will eat anything: bacon, celery, 3D-printed veal, the detritus of last night’s Sunday roast, stale pastries, books, shoes, circuitry, dice, the cartridges for your security team’s plasma guns.
7)Once the property of a bad-tempered gambler, Engine has now become the spoiled mascot of the engineering crew. In exchange for their adulation, Engine spends all his time defending his namesakes from mice.
8)If someone could just harness the kinetic force of Sunshine’s tail wagging, it’d be possible to power the ship forever.
9)Some animals are built for love and others are built to inspire fear. War’s owner was clearly hoping that their pup might grew up to be intimidating. Spoiler: he didn’t.
