The incorporation of the "R" into the house in #7 was very imaginative. I would love to see some more design ideas. I like the colors, the font spacing. I am shooting for a 'classic' look. The font in #8 has caught my eye, we could try a variation on the type face.
One idea would be to substitute the "R" house for the "R" in 'rennhack'.
Thank you again for your submission, and I am looking forward seeing your other design ideas.
