He's fine. Definitely looks like he is going into shed. Leave him be for a few more days and you will be surprised at the "new" Oliver. Just an FYI on the process - You will notice some dulling of his colors first, then his eyes will turn opaque or "Blue" (may be happening already in the pictures). This will disappear in a day or so, followed in a couple days with a shed. Mine typically shed during the night leaving me a nice surprise in the morning.
Make sure your temps and humidity are good. Maybe bump up the humidity closer to 70% and all should be good. If this is occurring on a feeding day you can go ahead and try to feed. He may eat and he may not. Leave it up to him.
Good luck!
