Some concept art of some convention badges I'm going to try and make for myself. All hand drawn and coloured with alcohol markers, with some using gel for some added shine and glitter effect. Funny enough this started as a way to try my new markers.
Markers blend really well, though some had to be redone (Twilight and Rainbow Dash) and the gels really add some little effects to some of them. I have also considered making them into stickers, but that is if I can get some good quality copies of them (and a way to make stickers).
For now, until I have something to help make convention badges with, I just have the concept art. With the naked eye, they look amazing, so the photo doesn't really do them justice.
