let me know what you think
I think a lot of people are "being too polite", and not giving you any real criticism here.
Please take this with a grain of salt...
In general:
IMHO -- aesthetically, I don't like 'em. I'm having a hard time looking at them. Too many angles and straight edges. Foremost, your cabinet shape isn't my "cup o' tea". The marquee area (top protrusion area) jettisons way too far out. It's like this massive wasted space, that really makes the entire thing look too clunky for trying to be a slim cabinet. If I were standing in front of these cabs, I'd feel like I'm about to be swallowed up by them. I'd probably get a forehead tan by the marquee light! In fact, both the marquee area and control panel are way too big for my tastes. On top of being big, the marquee section itself doesn't fit the small marquee mounted. So you have this ugly corner sticking out below the marquee, very unflattering.
To me, these cabinets wouldn't be categorized as slim, which kind of makes it pointless for them to have LCD's.
The triangular angled shapes are the second thing that bugs me, you have this sloped bottom area that's only purpose is to counter-weight the top area. It sort of makes me feel that I should be resting my knees against it, but yet, because of the CP depth my knees wouldn't reach!
You're also missing t-molding. T-molding is a must, if not that, at least paint the edges another colour. It highlights the angles better and breaks up the monotony in the colours.
Speaking of colours, the red and blue choices is really hard on the eyes. They're too bright together, and the little bit of colour you have at the base of the cabinets just looks like a last minute addition, again, to break up the monotony. Yet fails because it's the only thing on the cabinet that draws your eyes away from the radioactive burning of the red+blue, and just isn't interesting to look at. The colours just don't work.
Donkey Kong:
Aside from the general comments above, the CP doesn't make sense to me. First, the joystick is resting way to low to be comfortable. Second, the 2 buttons being so far from the joystick also looks uncomfortable. Third, there is so much unnecessary CP space for 1 joystick and 2 play-buttons that if I were to pass by this cabinet I'd feel intimidated to go up to the controls.
Galaga:
CP layout, again doesn't look comfortable. The trackball could have been mounted below the plexi top, so you don't have the ugly black square bracket showing, this is just lazy. As well, I'm having a hard time understanding why you put it to the far right instead of center? This is going to be hard for a lot of games to be controlled from that angle, and by the looks of the other cabinets, you don't seem to have a problem with the play buttons being far from the joysticks anyways. So why not put the trackball in the middle? Also, the start buttons are lower down the panel...which is inconsistent with the positions on the other cabinets. For the colours, at least you did a bit of a design on the side panels...but the front panel artwork seems out of place compared to the simplicity of the side-art, as well as being positioned too low. Again, it looks like this decision was made in haste, or as a last minute addition.
Marvel:
It looks like the top areas needs just as much artwork as the bottom half of the cabinet. It's like you went half way with the artwork, then got lazy to finish it off. I only say this because the artwork you've pasted on here is so rich in details, that the black space on the sides feels really empty and unfinished. It would have been better to center it, so the black surrounds it like a frame.
The player start buttons being on the P2 front side of the CP would be annoying for me, and I'm not certain why there's a single red button above the P1 joystick. I also don't get why the middle button for each player is different (white base)...
Overall, I cannot say I like these cabinets at all, nor would I pay money for them. They have a lot of design, aesthetic, and ergonomic issues that I would have thought out more thoroughly before mass producing.
This is of course my honest opinion, take it as it is.
