Threw this one out at the office today. Only day of the week without lectures. Feels great to take some time out for self and free one’s mind with a random sketch. Found this blue paper lying around on my table. Took 2 gray markers, a bic and a red pencil. Oops almost forgot. A white pencil too.
@ Alexb92: I have also been using Viper’s “PS rendering on a photo of a sketch” technique and it is really fun. Nice use of it (and I do love those felt-tip Papermates as well)!
