Nice! What kind of pad is it? Depending on the two layers inside, they might have a pattern on the side (like plywood) that would help better indicated it:
Thanks for the feedback guys! The pad has two inner layers the first one being EPAM (Electro active Polymers) and the second one behind that is a dielectric pad to transfer current into commands for the EPAM to follow. This is apart of a remote massage product I had done for school.
Edit- Added a foam and metal texture to the sides of respective pads in middle.
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)!
