You´re welcome BrandNut : )
I´ve take advantage of my lunch time at work and done revisions and new submissions:
1st based on your comments: #36, #40, #41, #42, #43 (about this last one, can you explain better what do you mean above please?)
2nd new submissions: #37, #38, #39, #44, #45, #46, #47
Do you think a bulb, student hat, book or pencil can make sense in the design? Not all together.
I´m at work but i can read your comments. Feel free to give suggestions please.
Thanks,
João
