Dims, I'm not trying to be smarmy (moi?) here, but I wonder if you'd consider printing off a number of those as greetings cards? The cute, inquiring little guinea fowl is so nice, the lion's magnificent, the baby giraffe has the 'ah' factor, and the ram is funny, in a nice way. I don't know what sort of shop the Zoo has, but I bet if you offered, say, a pack of six to them to sell, they'd buy them in. I would definitely buy them, and if you DO make any greetings cards from them, I'd like to be your first purchaser, please! I reckon if you offered them to the Zoo for post cards, posters, promotional material, etc., they'd be interested in your work.
