supposedly elephants have a really good memory

Theses are some prints i've been working on for the past 2 months or so. Again i'm using the three primary, but i ran out of zinc so i used plexi for the yellow. Obviously the first one is only red and yellow. I'm also playing with the shades of my colors...adding white or darkening them up. So far i'm pleased with them. Might start inkin 'em up in different colors just to see what happens. Tell me what ya think.
