Is this setup okay?

I’m wondering if this set up is okay for my 6 month old and I? I’ve added a top sheet because the breeze is getting cooler at night and I don’t like having baby in a sleep sac because he’s less mobile in it. I don’t tuck the sheet in because I want him to be able to flick it off if needed but he really doesn’t move in the bed at night. He’s a boob barnacle.
