Basic ideas from different a/cft's cockpit. A320's overhead, B747's chair and window. B737's EFIS panel and master warning sign. Self-made pedastal (I don't know which variation it comes from...). B737NG's MCP and Bombadier's PFD panel, right? Reminder: Commercial a/cft with yoke should be a side-stick. A good work.
Awesome work! This is a really nice drawing! The window frames look like they were taken from an Airbus A320 family aircraft. The MCP, EICAS (On the captain's side outboard DUs?) and throttle quadrant looks like they're from a Boeing 737NG. But the trim controls, INS, the center MIP and the center sticks just look out of place. Nonetheless, this is an awesome drawing.
