Small Abstract Studies in Acrylic

I have just had 2- 4 feet by 6 feet canvases made and did these small studies to decide if I am going to use these small studies 2"x3" for them. I loved doing them and the bright colors and the textures have lots of movement. They are on archival media board that I have gessoed, painted upon in acrylic and then varnished. I have them with a small mat which has a very wide border for more impact. Knowing whether or not they will work on a huge canvas is a bit risky...but what the heck? What do you think?
