So I'm making a mancave sign as a present for my dad. We're going to transfer the design to plexiglass, color with stainglass paint and put it in a box with a light under it so it will have a light up sign effect. Cool beans. I'm having trouble with the overall design. I picked out a font and my dad found a graphic he really like, but I'm just struggling for a good sign look and all the empty space. Here's what I got so far. Help?
