Here's my take on greyhound art - realize not all people are like me (that's a good thing )
If the art is of a particular dog, I'd like it to be my dog, not somebody elses. If it is general greyhound art that you can't tell that is of a particular dog, that's fine.
I have note cards I won at Wonderland the first year it started the expo - on the cards are a picture of somebody else's dog. Not something I'd use since it isn't my dog.
As a gift, I was given note cards with a blue greyhound on it, not somebody's actual dog, but a general greyhound.
Realistic, but not personal is good if it isn't my dog. If it is realistic and personal, needs to be my dog for me to display.
