One that worked and one that didn't!

I have been playing with some new techniques-eggshells on ceramic tiles, alcohol ink, embossing and embedding and finally pouring resin to seal everything.  A couple of weeks ago, I tried doing a 4X12" tile, but got the background color so dark the later butterflies hardly showed at all.  In short, it's a mess.  Decided to try it again and the second project is much better and has given me an idea of how to modify this kind of design and make it work.  The second one, just finished is a 6" tile, also using eggshells, MUCH lighter background and butterflies that actually show up!  Two are embedded metal charms, the other is an embossed heavy paper piece.  I sealed this one with resin, which was a messy process, but it looks like it worked!  Learning a lot here!
