I also think the drawings are fantastic! I can't draw a straight line with a ruler, tho, so maybe I'm overawed?
Here's a suggestion (and you might already have this so...) Why doesn't your husband post some of his art on a website so people can see a sample? He could do different sizes for different prices. I can't afford it but if I had the money I would pay $30 for a drawing of my baby. I had the art teacher at school draw a pug for my daughter for Christmas but he drew it on manila paper and did a very quick job, so it wasn't "professional" BUT the picture was awesome even at that and my daughter loves it---with that in mind, your husband is using quality paper and other materials, he should definitely charge for it if he's going to sell it! Good luck!
