I like #70 ... the only thing is that the computer screen inside the circle looks a bit more like a TV with the three buttons at the bottom. If you could change this to make it look more like a computer / computer screen that would work better I think.
the only way i can submit once it is in judging mode is to be placed (at least temporarily, while I make submissions) in 1st place. If you would like to see those changes, that is what would be needed. Please private message me if you want me to make those changes in preparation for that. Thanks for your interest.
