Here my designs and there's 2 version on the illustration. (one with the wrench swinging around the finger & the other one holding it). I have seen some messages regarding contester doing derivative works from other designer/directly using their designs, so I figured out that I should submit my own model release to show that it's indeed my own artwork (as attached sketch).
For the design, I have tried to use minimal amount of colors (the website consist mainly of cool colors) so that the design will match and not overtake the main logo too much.
Hope you will like it and looking forward to receive your feedback.
