#23 and #22 - I like the shape of the logo with the rounded and sharp corners. i also like the shading/bubble look on the upper left. I would like to see you add "San Jose" and 2012 to the logo some how. These are important elements to include.
#21 and #20 - I do like these - I could almost see using #20 and #22 - depending on if I was using them on the web, on a flyer, in a brochure, or as a lapel pin. I do need you to add "San Jose" and 2012 to these.
Dear CH, thank you for the comment. I have revised the design by adding the "San Jose" and " 2012" into the design and also, I have submit another concept. Please feel free to comment or ask. Thank you. Cheers.
#35 - overall I like this, but I am still having trouble reading "California Science Education Conference" against that earth background. I am open to ideas on how to make this part more readable. #39 - there is a bit more room on this one - can we try replacing "2012" with "Oct. 19 - 21, 2012"?
Dear CH, thank you for the comment and feedback. I just submitted a new concept and introduced the sphere shape. Please feel free to comment or ask. Cheers.
