Refining the logo

The services of a graphic designer are required. It is necessary to process and bring to mind the originally designed, but not completed logo. Wish: hats should be slightly elongated (multiple), respectively, the hat floors should also correspond to the size of the hat itself. The lights on the hats and masks should be correct. More than a sample with wishes in the drawing that is by hand. The logo will be used on a black background, this must be taken into account when editing chiaroscuro. I would like to warn the artists that the prepayment will be made only after the first samples are submitted (i.e., after the first results that suit me).
