Your titles are key word soup and in some cases are contrary to your descriptions.
An example:
"Limited edition mouse drawing, black ink, illustration, animal art, nursery, christening gift, countryside decor, cosy home, cute print"
I read this and thought "Oh, I guess he's going to draw this several times but then they won't be the same." And then I read the description:
"This lovely limited edition print is a simple yet charming depiction of a door-mouse in black ink. One of only 50 prints double mounted and wrapped in cellophane by a local business."
Suddenly the the drawing is a print. I felt like I had been baited and switched. On top of that you're farming it out which makes the whole thing much less personal.
Then there's this:
"This artwork will look perfect in any part of the house and has a classic, clean and sophisticated look about them."
I once read some advice for people writing personal ads. It said "Don't say 'I'm funny' but instead SAY something funny." Same thing here - don't tell us, show us
