Hi! this is my version for your logo! High symbolism icon - the overall look shows an eye expressing the visual part of the icon and yet if you tilt the head it looks like a symbolic human, divided in 2 parts representing the bonds created by the trainer with the trainee. The icon was very carefully thought about, so you can have a high symbolistic feature to your logo, that is easy to represent in a schetch. Also the color scheme can be changed if you dislike it. Please provide feedback for a satisfying colaboratin!
