Painted acetate over Oil paints

I did this card for my niece and her husband for their birthdays (they are only a couple of weeks apart). I have been wanting to give oil painting a try and this was the perfect opportunity for me. The very back is a piece of canvas card that is covered with gesso then painted with the oils, which, of course, took almost a week to dry. I decided to "slap" some VersaMark on it and emboss it with clear powder, just to make sure that it is preserved. The 2 acetate pieces are stamped with StazOn. The middle layer with Cherry Pink (sun) and Azure (bird), then I colored the back with Sharpies. The couple on the front layer is stamped with black StazOn and the bird, again, with Saddle Brown. I then painted them with acrylics. To bring the piece together, I used foam tape between the layers and roof flashing tape for a frame. I also put silver corners on it for a splash of style.
