Thank you for the invite once again! Here are three designs a bit different from what you have now on your contest,...with three different styles:
#131 - classic appearnace, with recognizable initial. #132 - contemporary looking, easy to transform into earrings, medallions, etc.,...green/blue on rund shape to symbolize global segment of your work! #133 - three symbolic figures, making the jewelry,...might be interesting concept.
Hope you'll like some of these, and if you see some space for improvement, don't hesitate to let me know! Thank you!
