Initial Sketches- trying to draw collections of animals

I have begun by sketching some animals just to get started. My purpose for these is just to explore the subject area a bit without trying to focus the idea down too much. I want to see what works and what doesn't work. I actually like parts from each of these sets of drawings that I have done, they each have moments of success within them. However, the thing that I keep referring to is how these would work in print. Print is important to my practice, especially screen print where only the second set would transfer into screeprint well.
