Your designs are great. You have included the element of water which is important. The words 'GREEN Educator' need to be together together. GREEN is a program (Global Rivers Environmental Education Network) and a GREEN Educator is a teacher within that program. Really like the feel of your designs though! You may use the official Chevrolet's logo typeface for the word Chevrolet. Thanks!
Thank you! I have uploaded new verions with your requests. Solution for GREEN tries to make it Chevrolet/Green for upper part, and Green Educator Award together by color.
