When I created my one-letter-a-day-project a couple of months ago, I developed a new style inspired by neon signs & the 80's.
I wanted to have alot of details and eye catching colors.
I created the numbers in Cinema 4d, and then I did all the postwork in Photoshop. There was no weird light setup made in C4D, all the colors are created in PS, with different masks and blending modes. I won't make the rest of the numbers since I'm busy with client work, maybe one day!
