I'm not sure I understand the question on the angle of the button layout. If you mean the curve on the layout of the six buttons - I simply placed my hand on the blank for the control panel (having already mounted the joysticks) and marked the positions where my fingers were most comfortable. This formed a shalow arc for the top row of buttons and I mirrored this for the bottom row. It feels comfortable to me, and I used the same layout on the 60+ other CandyCabs we've made without complaints so I guess it must work.
Please don't take this the wrong way as I'm just trying to provide some helpful feedback.
That CP layout is horrible. The buttons are too far apart and the angle would be murder on your wrist. I know cause I have played on it many times.
I play fighting games at the competition level and I have never even once seen a player that prefers to use a layout that slopes down from left to right. Players always use a layout that either rises up from left to right, or one one that is straight across.
I guarantee you that any serious fighting gamer that bought your cabs would immediately toss the CP and replace it with one of our own. It's no big deal as we do it very very often with wooden cabinets. I did it with my cabinet.
I highly recommend you read the article on slagcoin.com that breaks down the different button layouts, and the rest of the site too.

http://slagcoin.com/joystick/layout.htmlWhat type of joystick and buttons are you putting into these cabs? Looks like a Super Joystick and some kind of competition pushbutton. People who are candy cab connoisseurs HATE these controls. I can't stress this enough. Go on arcadeotaku or shmups.org sometime and listen to some of the diatribes people have against them. The fighting community in the US is fine with a competition joystick and buttons. A super joystick is unacceptable.
The mounting of those joysticks look way too tall. They are designed for mounting in 3/4" or 5/8" mdf. I'm guessing they are mounted flush with the plastic and that's why they look so tall.
IMO though a true candy cab has either Sanwa or Seimitsu parts. Accept no substitutes.
I would add some pics of the cabs setup in sit down mode since that is what any candy lover loves about candies.
Also, can those ELO monitors do VGA?
Other than these criticisms these cabs look very very nice. Great paint job and a slick finished project. You just need to be more in touch with what your potential buyer is looking for.
