One step forward, 3 steps back!

Okay, I added a layer of mango glaze to my 3 5x7 canvas boards... Hated it!  So, I'll be starting over on those... The 10x10 stretched canvas, however, is progressing.  When the coat of matte gel medium dried, that I put on the tree drawing, I thought it might get lost in the other elements (a photo, vintage poetry and maybe some stamping), so I got out my colored pencils and colored it dark brown.  It shows up much better now and hopefully it will stand up to some glaze and other collage elements.  What do you think?
