Looks good :). This is pretty difficult to get together. I glued one side and one piece first (the long bit) and then worked from there. I used the second side to stabilize it so it was the right shape, then glued on the top two pieces. I would recommend against using super glue for this build, you will need some time to adjust here and there and ca glue will make things too difficult.
To make the tail and engrave on both sides. I flipped the design, then used a chipboard template to cut out the shape, put the tail in (reversed) and engraved. For the tail, don’t use the default engrave settings or the wood will be way too thin, cut it back quite a bit (I forget exactly what I cut it at here, but it was a lot less) mostly you just need to burn off the paint.
Used the program in this instructable to make the main part of the box, then a lot of editing to get all the pieces to fit together.
