Sugar Skull Shadowbox

Collage art; my sugar skull illustration.  

Sugar Skull 61: 5" x 5" x 0.75" (this one is the original illustration)

Sugar Skull SB14: 5" x 5" x 0.75"

These three would make a nice grouping as they are different sugar skulls with similar sized frames:
Sugar Skull SB12: 7" x 7"
Sugar Skull SB14: 5" x 5" 
Sugar Skull SB15: 6" x 6" x 0.75"
Sugar Skull SB16: 6" x 6" x 1.25"
Sugar Skull SB17: 6.25" x 6.25" x 1.25"
