Yep he's going into shed alright. His eyes are blue.
Right now, it may be best to bump up his humidity a little.
How many hides do you have in the viv? It may be best to get another, so you have one on the cold anf another on the hot side.
Also those wooden hides are not very good IMO, they nake the BP feel less secure bacuse of the wide opening whivh let's loads of light through. I prefer the ones from exoterra, specifically the large ones for the adults) It looks like this.
You can get smaller ones for younger snakes. All my snakes use them and they are really easy to clean as there is no risk of mould.
Hope this helps, and it's a cute little snakey. Good luck!
