First might be too close of the "energy saving" campain from Canada Gouv... so I ajusted it and transform it to a "S" shaped leaf electric plug. Hope you will like it !!
I like the concept and the colors you are using. The combination lightening bolt / plug is nice. Entry #18 almost makes the logo into a character, which I never thought about but am beginning to like. I see you also took a look a the new plugs that are coming out and tried to work that into #19. Although I would like to use some sort of that plug if possible, the character evolving in #18 just seems to work much better. Thanks for all your efforts.
Thanks for the feedback... yes I love this character too... it give some life and energy to the design and it will surely do the same to any of your advertising campain. Many possibilities comes with it. It might also be an interactive character for TV commercials and a Website and DVDs navigation guide. It can also have is own name...
Seriously, I think we have a very good concept here and I am pretty proud of it !!
