DIY humidor Shakuhachi case

I've been working on a shakuhachi storage cabinet and now it is almost finished. I have been keeping my flutes in bags until now to keep them moist. Blowing in the bag to keep the moist level's up. The climate here is a moderate sea climate, and ranges from 35% moist to 55%. Winters are more dry. Those numbers are a bit too low. I've found myself a nice display cabint of Philips electronic gizmos and turned it into a humidor.

The first photograph is how I got it, painted black and rusty at parts. It was originally blue with Philips logo's on the plastic windows.
Unfortunately the cabinet was a bit too short to hold my 2.55 Mujitsu and Kyotaku 2.55 flutes. I have altered the cabinet like this:

cutting open the top part and folding it in, to make the room larger. On this picture you can see both the 2.55 flutes I have. The moisturizer I put on top to make room below. It is called 'oasis' here and is intended for flowers and plants.
The final result can be seen in the last shot. I painted it with a rust-paint, added a carpet on the floor. An voila a nice humidor! I used to smoke cigars, but lurking on the flutes is a tad bit healthier. The last thing I want to do is close the small gap between the door and the frame. The moist levels are better now, and even more nice: I can easily pick one flute and play!
