Thanks for the feedback! Okay, I've tweaked it a little and moved the 4-way as suggested. Do you guys think this is far enough? I'm trying for a symetrical layout, but obviously have room to move it more if I need to. I only bought 24 buttons, so I will hold off on the 7th button for the 8-ways at the moment, but have room to add them later if I miss them.
Also I've played around with the art and have 3 ideas.
The first is a template I made for the layout which I plan on using for construction purposes.
Next to that I added a flame border and the flames on direction arrows and around trackball have gradients. The 4-way direction arrows are red here.
Bottom left is sans flame border w/gradients, yellow 4-way arrows and red 8-way arrows.
Bottom right is all line art and silhouettes, no gradients. And red player 1 arrows and yellow player 2 arrows.
So any suggestions or opinions on the art or layout? Thanks again!
