I'm wondering what #7 would look lke without all the sun rays? I like it, it's just a bit much for me with the sun rays. Also - I can't read the words Learning Systems because of the small font - but I'm not sure what the fix is there.
#25 - Can you lighten the background up a bit? And can the font on Learning Systems be a little larger. My concern with this one is that the name of the company isn't really the focus. I do really like the design though.
