I've uploaded some new wing options -- more opaque white, adding some blue, and solid white. Also, played with a punch of blue behind the bee, as well as the arrangement of the wings. On a personal note, I think #27 and #25 are working the best at this point, but definitely looking forward to your feedback.
Showing you two versions. #62 is a straightforward gray scale version (the original design simply reproduced in gray scale). With #61 I created a version that eliminates most of the grey tones, for a more black and white effect.
