Just an opinion....don't kill the messenger...
If you are building an "arcade cab" then why are you placing images/icons/etc of consoles?
Its an arcade cab...find characters from arcade games...
Yes, my cab has the console games, but I consider those a perk...
1. make a theme
2. base your artwork around that theme
3. its your cab, so make it however you want it to be...its going to be in your house/business/etc
Me, tell the truth, I was quite impressed with the "freeplay" marquee( 1st image you posted)....nice work...
I remember I went through this same dilemma when i was creating the marquee for my cab...
trust me ...don't overengineer it...
I love it, looks great
