    Looks quite nice.
    Huge board, very busy with lots of useful text.
    Gold colored plating - Electrolysis Nickel Immersion Gold (ENIG)? Shooting for RoHS compliance? This type of plating is a good choice and I use it often. Easy to use to compared to other RoHS platings.
    J120 (ribbon cable type connection) looks to have enough room at the ends for a shrouded header (boxed in connection) to keep connectors from being off by a row or two. If you can fit in a connector in with ejectors then your customers would love it... but the heat sink below it might be a little close.

    Shrouded headers - excellent improvement over the naked headers and saves a lot of headache from having headers off by a row or two. Headers with ejectors is nice to save on ribbon cables but not a must have... just something to keep in the back of your mind. I did notice your earlier boards were not shrouded but I also noticed they were so full that there really wasn't any choice.
    Strange that the software shows the pads as yellow - I thought for sure they were the ENIG type plating (which is kinda pricey). Although it is nice, there is no need for this type of plating for a pinball machine. All my boards for work are ENIG but my pinball boards are always the old standby tin/lead plating. Just can't beat that for cost/performance.
    What software did you use for the rendering of the board? My Mentor PADS doesn't do nearly as nice of a job at rendering images and it always looks like a throwback to the 1980s.
