A Little Experimentation in Shading

I recently read a post on Lydia's blog Understand Blue about a technique using white pencil for shading an image stamped on dark paper.  So........ I decided to give it a try.  Of course I think I found the smallest possible image to work with and should have kept looking but I made do.  (This is a recent Stamp of the Week from Unity.) 

So I cut a few pieces of black and a few pieces of navy cardstock and stamped the image on them in white craft ink.  

After I let that dry for a while I went back with a white Prismacolor pencil and added some shading and reinforced some of the image, like the dots, that appeared too light.

Here's the same image on Night of Navy cardstock.  

I was going for a simple card and took out a white card base and added a panel of dsp.  The pink you see is some washi tape that I had out on my work table.  The problem I ran into with that was that it was too opaque to successfully just adhere it to the panel on it's own.  So I cut a strip of white cardstock and put the washi tape on that.  Then I cut the strip into three strips and the rest is pretty obvious.  

I'll finish the other images and make them into cards also, sooner or later.  But I think I should look for a larger image to work with next time.  

So let me ask, what would you use this card for?  Birthday, sympathy, or would you think it might make a nice bridal shower card?  The sentiment will go in the upper left corner.  Inquiring minds would like to know.
