For your logo I decided to create a fun and modern graphic of a 1950's style teacher standing by the blackboard/logo with a chalk in her hand.
The font for "classroom" is a font with a retro feel, while the rest are more modern, to distinguish the logo with its own personality. The "o" in classroom is part of the icon/branding provided.
This has a fun feel, while still maintaining the branding of your company.
Like the look of it but it is probably a little too feminine. Any other ideas to replace the lady with something else? Love the font, symbol utilisation and background shades!
Or maybe a bartender, something unisex as we wouldn't be able to use the logo the way it is (as much as we like it) because we would lose the male demographic.
I changed the silo to one of a bartender (I think that is most appropriate?) holding a tray with a bottle. I added stars and played around with the tag line, emphasizing "astronomy" in the word Gastronomy.
