Currently one of its kind café in Finland, Manga Café, is holding a competition for sort of new mascot or website emblem (or well, the site claims vaguely it's a 'logo design' competition which it isn't if they're asking for a drawing). What I made was for my own enjoyment and illustrator practice (I almost like you, illu. ALMOST) but I thought that why not, I'll suggest it for them even though it's very different from their current 'look': http://mangacafe.fi/
Aand frankly imagining how I could improve their look it got kind of out of hand in my head!
I even started sketching an actual logo for them (drawing is not a logo, dammit! NEITHER IS THAT PAPYRUS-LIKE FONT THEY GOT GOING) and even at the risk of sounding like a complete douche, I sent them email where I told I could help improving their image for free, as kind of a project. It's also kind of stupid of me to suggest something like that, since I'm just a student and I have never designed a complete logo or identity for anyone, but I'll never learn if I don't do things I guess!
