welcome to the competition - it is nice to see new input. I like your inputs and will put them up for review among my colleagues. As for #53 - we do not use hats for graduation in Denmark which makes #52 more relevant towards a possible logo.
You seem to have some really good ideas (from your portfolio). I like the "The Community of Pittsburgh" logo. Could you - in a horisontal logo (like your Business Interior - logo) - make an icon that signifies sports and teamspirit/social gathering through sports? That would be awesome - I like your work so far.
As I said #52 is the most relevant of your two suggestions and we would like a logo that could be a standalone icon and an icon with text. Could you make an icon that represents movement in a broad term?
thank you for your feedback, here is the new proposal, teamspirit/social gathering through sports. I use yoga, football, and mountainbiking as the representative of sports/team sports, the circle is to empower the networking among them, stars are the quality result of ideas, thought and development of the group/forum
