Here's my attempt at Geo Force. I know this outfit isn't the most popular but it's the one I remember him wearing when I read The Outsiders during the 80's and it remains my favorite.
Pretty standard recipe, DCUC Owlman with a modified Indigo Lantern head.
The logo was added using decoupage with decal paper. I had trouble finding a template so I used a slightly deformed comic image and edited it with Gimp. I'm pretty pleased with how it turned out.
I hope to add a couple more pictures in the next few days.
I hope you like him :).
