Re-discovering Brass Stencils

When I participated in Stamp a faire this last weekend, I re-discovered some toys I had previously put away:  my brass stencils!  So I dragged all of these out, including my light box, and had a little fun.  Here is the first card I made, using the faux ceramic tile technique:

This vase is stenciled onto light blue cardstock, with the diamond accent stencil adding pattern.  It took me a long time to figure out what to do, since I had not done this technique in a long while.  And I can't find my video from Dreamweaver Stencils.  I had a very good video showing all the steps, but I don't know where I put it.
    But I persevered, and I think the results are quite lovely.  The Hero Arts greenery stamp is stamped with Bamboo Leaves Memento ink over the diamond stencil.  I sponged clear embossing ink over the top of the vase and heat embossed with clear powder.  That step really made the blue of the paper pop.  (In a day or two, when I am finished with another card using the same technique, I'll show again this lovely light blue paper.)
   I used the vase stencil to make a background "frame" for the image using a tiny print scrapbook paper.  What do you think about the duck?  Should I lose it?  I am undecided.  I think the card needs something there, but I am not sure about the proportion of the duck.
         Here is a list of the supplies I used:  green Hero Arts notecard, green print from Basic Grey 6" Kioshi pad, Dreamweaver vase and diamond pattern stencil, Dreamweaver regular embossing paste,  light table, Hero Arts Exotic Bloom (H5424), Memento Bamboo Leaves ink, Colorbox Top Boss clear embossing ink, Toybox duck rubber stamp with Memento black ink on white card, Copic markers,
        This card looks cool in tone and peaceful.  I am thinking I might make some wall art from the stencils in this same manner.
