Hi!! First of all both of the pets are drop dead gorgeous omg Now, I don't know if you want intricate design ideas, if so you can stop reading here :P My pet profiles are on the simple coding side, hope you can take something out of my suggestion.

This is what I picture for Cold War: my immediate idea was to have two separated text boxes for the stories, maybe one above and one bellow the art. I also imagined them to be round or rounded, looks more organic imo, like the pet. You could add smaller/different sized boxes with the rest of the content around the art, with a very dark pattern background or a bright/clear nuclear winter background to contrast with the pet art. The boxes could be a darker green to blend well with the design, making everything seem like one thing.

I feel you. I am so bad at designing profiles! I'm like, do i do squares, circles, hovers, pages, left right up down?! haha. I usually start by deciding what I want featured the most and make that part the biggest. :) lol I'm not very helpful, sorry. this is why my profiles suck
