Happy Birthday

I made this card for my husband whose birthday is today. I really struggled with the coloring here. I asked my husband who is a big fan of horses and knows quite a bit about them what kind he thought this might be. He thought for a long time and then said a cross between -- and proceeded to name three different kinds of horses I'd never heard of. Oh, well. The one thing I was really pleased with -- and you'll either have to look at the smaller picture or click on the big one to see it -- was the detail I added to the tail. I unwound a piece of twine and added it to the card with some glue.
The stamp is by PSX and the paper comes from the Vintage Collection of Hot off the Press.
