Thanks for the veterinarian, animal doctor keyword suggestion, Mike, I'll add them in.
As for the caption being left in or out: it'll be easy for me to remove it, but should I also have a version where it's left in, or just a single version without it? What is the consensus, please?
Again, feedback is welcome. It's easy to lose perspective on one's work. This is my first piece featuring a domesticated cat (BTW, Mike, the cat is a breed called a Ragdoll, and I've included that in my keywords), and I did this piece specifically because I'm trying to create work that's more appealing to the public, and of course dogs and cats are always popular. Or so it seems to me.
Thanks, everyone! As per your advice, I've added both versions, and put in a few more keywords. On to the next project! (And if anyone else chooses to comment, please do. Encouragement/critique is appreciated as well).
