I have problems getting 2 hinges right, and you used 5? Really? Even a military footlocker only has 2. I would have done it different. Two regular hinges, and a chain to prevent the lid from going too far back. Either that or just a lift off lid. I like to keep things simple, at times, especially things like boxes and chests.
As for toy boxes, I do not like lids on them at all. This eliminates the possibility of a lid slamming on fingers or a head. It prevents a kid climbing in, then having another kid shut the lid and sit on it. Plus a small kid often has trouble enough just putting toys in a toy box, let alone messing with a lid. Once a kid gets older it is simple enough to add a lid, so it can be used as a seat, either lift-off or hinged.

.....Call me a craftsman, artisan, or artistic, and I will accept that. Call me an artist and you will likely get a quite rude comment in return. I am not a @#$%ing artist.
