Sorry, i can't see a difference between #19 and #18. I really like entry #2. Except in all 3 designs I am not a fan of the tiger striping in the inner circle and the roof of the house. And the blue is showing as a primary blue color. Which I am not a fan of.
Can I suggest another edit? The middle circle between the grey and the white- can you change the color? It's too startling. Not sure what color to suggest. Sorry. And can you switch the house/sky? Can the house be grey and the sky blue?
