Personally I like a bit smaller egg doors than what you have, trying to compromise between keeping the rain and other weather out (to keep the coop dry) and getting a hand full of eggs out.
Having the ramp with the angle built in is good, but I would have to have bigger egg doors to accommodate that. And as the trap will be in the coop side, I need to pull the ramp to clean through the egg door, front or back, but probably front. The single flat board on a teeter totter type pivot point, in my design, resting on a rod (crossways) is the best use of space, weight, and efficiency for my purposes. Yours is a great solution as well.
