Zinnia Polka original still life painting

I couldn't resist doing another zinnia painting before they are gone for the season. I consider blue bottles a part of light therapy so keep them in the window for catching that blue glow. This little Vicks Salve jar is one of my favorites. I actually remember when they came in the glass jar. I think we had the same one all through my growing up days. I'm experimenting with a gel retarder to keep the acrylic "open" or wet longer. The problem with it is it has a terrible consistancy and is hard to mix into the paint evenly. Any one out there with experience and advice for this material? Acrylic on 7 and 1/2 inches by 8 inches gessoed masonite. SOLD
