Your sister is gorgeous ! I think if you we're doing photos of your sister you should take them then simplify them on photoshop. So it's not too photo like on a business card... Like the others said your work can be seen online..but I definitely think an image is effective.
I used to study graphic design and I agree with some of the comments as you don't want it to be too fussy but you want it to stand out and not just be words also... I like something in between..
I think for certain areas of work an image is ideal.. Eg.. Cake business a simple vector image of a cake in the corner or background.. But not an estate agents you wouldn't put a house on.
If you get me?xx
