I like what you did with 103, but I don't like the book inside. I also like 104, except for the book. Could you fit a little house inside there without making it look like a home builder?
I'll be working on it, but not sure about the little house inside, since I can see another entries with the same idea. Let me know if it's your concept, or it may be obvious? (BigEd HOUSE)
I think it may be obvious because of the "house" in the name and the description. I definitely don't think you're stealing. I'll tell you my opposition to the book and the graduation hat: the book is so 20th century--this is a digital company and concept. The graduation hat implies this has to do with students, and it doesn't, it's all about training for teachers. Maybe that helps you think of something different?
