I think the Idea is ok.But the font and color is not OK.Use other font and try different color.OK? nice try.
I like number 2. i think another good design might be number 2 with number 4's background. Just an idea. I like number 8 as well but to me number eight looks exactly like number 2 so......lol Any way if you could try to make number 2/8 with number 4's background i think it would look really neat!
