Birdhouse Stamp

I got this stamp at one of the used rubber stamp sales.  It's been floating around my work table for months now and I finally decide to use it.  This will be one of the cards (3 -4) for my class down at the Akiyama Wellness Center.  I wasn't too sure if I should use it for the ladies since it has a lot of fine lines and shading but I know they like a challenge.
I'm not sure why the photos of this card looks like a square when it's not.  I don't think I have my camera set on "square" mode and I don't even know if you can do something like that.  Hope someone knows the answer to this mystery.
