I need 20 original line-drawings to be done for a children e-book on bees. The topic/theme for all the 20 drawings are shown on the 1st slide of the attachment. And the 2nd slide show 2 examples of the kind of line-drawing expected: - simple, cute - in gif format, with transparent background - about 400 by 400 pixels, 600 dpi
