Great first drafts! I like the oval design in #13, maybe a little less symmetrical with some slightly "ragged" or "penciled" edges in the ovals. The font for "Zendavor" should be bold and fairly easy to ready, but with a little more flair - #12 is my favorite font so far, but without the shadowing. I do like on #13 how the Z is larger and "Signs and Graphics" is in the tail, but the "Signs and Graphics" is too subtle. The font of "Signs and Graphics" on #11 is interesting - kind of gives a little artistic feel. Try to incorporate a little black color in the design, too. Thank you!
