Nice color on the maple. It looks like highly figured walnut. The miter joints look perfect. One hinge appears to be sprung and holding the lid higher on one side. Also the screws came through the back on the other side. I have better luck morticing the hinges into the edge of the box and lid, than attaching them to the back. If the hinge is too high, cut the mortice deeper. If it is too deep, use a shim to lift it. I have twisted off brass screws and had to drill them out. I plug the hole with a dowel and re-drill the screw hole. You won't see this fix if you mortice the hinge. In hard wood like maple, your pilot hole needs to be larger than you would think. The screw threds should engage, but no more. I use a shank size drill at the start to prevent binding. Pre screwing with a steel screw is great if you can find one the correct size. I often use #2 screws and the local stores do not stock these in steel.
Its a good project for scrap wood. Save your wood and try another. Boxes are fun and they make great gifts.
