I have designed, coded and provided all content on reversecompatibility.com. This includes custom brushes, GUI (navigation bar), banner, etc. I have experience using Corel, Photoshop, even GIMP (open source art program). I have previously worked at a local sign company and screen print shop designing T shirts.
I would prefer to do my artwork with a digital art pad as it seems more conducive to showing my art style. However if something vector based is required for formal sign or banner design that is within my capabilities as well.
