Logo design for a highly creative brand

Information on the business: HR superheroes is a consultancy
Industry: Business
Type of logo: Emblem
Brand name in logo: HR Superheroes
Slogan in logo: (none)
Ideas for the visual style: superhero badge style
Things to avoid: cheap or gimmicky
Preferred colors: no restrictions but must be compatible with the brief
Where the design will be used: for a corporate market therefore must not look gimmicky or cheap
Extra notes: We have considered the two main types of superhero style and like the impact and colourful nature of the retro style like Superman but it can look too gimmicky. The alternative style is a modern superhero style, such as the Avengers ~ this style is shiny and corporate but loses colour and impact if it is allowed to become too bland. It's a challenge but we must get the logo right because then we can develop it to signage and brochureware. There is more work here for a freelancer who has a vision for the brand. Please ensure that the logo fits with the style we are using on our website. The first draft of the website can be seen at www.hr-superheroes.com
