Thank you very much for encouraging me and appreciate your advice.
For (1) and (4), I really don’t like to have many details about the stick or throttle, so I am trying to hide them using the pilot hands. One more reason is that they are different between aircrafts so that hiding them can reduce much of effort. I really want to use the dithering effect you've said, but I have not yet been good in pixel editor so that simply reduce the color range (somewhat similar to manga/comic drawing).
For (2), I have digits in one shade already, the single white dot on each digit is just the short line (marker) on the gauge. There is not enough space so that the digits are overlapped by those markers.
For (3), Yes, I have added some pedals' color, but for other unnecessary details (for example, the radio device), I decided to use radio communication balloons to hide them ^_^.
So that, the result becomes something like this (F-15C cockpit) :
I will improve the quality while drawing new cockpit, and brush up the old one when having time.
For me, what are called necessary (important) in basic-game-style cockpits are:
- Flight control instruments (ADI, HSI, barometric altimeter, radio altimeter, airspeed indicator (with Mach number), vertical velocity, G-meter, angle of attack indicator)
- Weapon control instruments (selected master arm weapon, remaining ammunition number of each weapon)
- Fuel quantity indicator
- Engine control instruments (tachometer, engine temperature)
- Radarscope (maybe integrated with map), target view camera
- Radar Warning Receiver
- Configuration control: Landing gear, flaps, arrested hook (optional), swing wings' angle (optional), thrust-vectoring nozzle angle (optional)
- Damaged status lamps
- Throttle and stick
- Radio chatter contents
- Flight clock
- Mission information, mission briefing.
