After taking a break.. I felt that I deviated from my original idea a bit too much so I decided to do another thumbnails based on my earlier thumbs (4,9,15) but I tried to push the perspective and distance.
Then I took it and reused some of the color keys that I like to use it as a base for the color. I think I will be going forward with 4A or 4B! Let me know what do you think or which one is your favorite!
