Pet me - GIF

Absolutely adorable. There's just a few things that I think could be improved. Also, please don't take me as a hypocrite ;w; I suck at art so much, I'm simply giving you some tips to what would improve this piece I guess..
-The dog on the right's tongue movement seems unnatural. I've had dogs, and usually when they lick they move their whole head.
-The dog on the left's eyebrows are a weird creamy colour, a dark brown would look better.
-The dog on the right's upper body is a bit big compared to the other part of the body, but then again, some dogs do have rather large ribcages..
-The dog on the right's tail movement is weird, usually when wagging it's from left to right.. Dog's tails don't have the capabilities to move up & down. Although, with some dogs with curled tails, it does seem a bit like it moves up and down. The white dog shown looks larger than most breeds that have curled tails, and the fur and build is different too, so I'm assuming that his tail doesn't curl. Ah, and by "curled tail" I mean something like this: www.rvwbasenjiclub.org/Curly-t…
Anyway, your artwork is absolutely beautiful and pretty much a goal aaaa ;w;
