I'm selling this design I drew with sharpie on a skateboard at a thing. I was thinking I would sell it for $40 but I would like any ideas if someone thinks it should be more. It is not my original idea, I got it from a video game, I wrote credit on the back.
Try using a black sharpie and thicken the edges of the main design...if you're feeling up to it you can try and outline the more detailed designs but less thicker.
Just seems more appealing that way, otherwise it's pretty cool looking already.
