The logo should have a mammoth character (nothing too evil or too childish either!) and some kind of football (soccer) icon to underline that Mammoth League is a fantasy football game. The mammoth character itself should also work on its own (without any text) so it can be used as an icon as well. It has to work well as white on black.
The mammoth character can be the main part of the logo, or quite subtle in the logo. We will consider all ideas.
It should have 'Mammoth League' as the main title, and then 'Fantasy Football' as the sub-title.
It should be viewable at small sizes (social media avatars for example) although there could be a simpler version for this if necessary.
The logo should work in full color but also work as greyscale (black and white).
The full logo sizing should be wider than it is high.
Suggested colors (there is flexibility - use any/all as you wish):
#a3232f (dark red)
#c9e5ca (light green)
A simpler design with fewer colours would be preferred to a complicated colourful one.
I have added images with some style ideas although a simpler design in terms of the character is preferred to a fully-detailed one.
Also, remember this is a logo for a football league so the design should have a sporty (football) feel.
I require full source .AI and .PSD files and .PNG files in a range of sizes upon completion.
