A) I love the pics
B) If the joystick at the top is a 4-way you should adjust the triangle/arrows accordingly, or are you trying to also reference the q-bert influence... maybe make the diagnals a different color then?
C) I like 1 and 3... 1 is more exciting, 3 is simpler without the dual images
What are the other colors of the cab? Such as buttons, joystick balls and especially the T-Molding?
