That is quite a bit of orange peel, so if you clear it without resanding, you're going to sand off a lot of clearcoat, just to get it 'flat'.
Your clear will only lay as flat as your basecoat.
So my suggestion would be to wetsand it down with possibly 1000 grit. Get the base as flat as possible, then clearcoat. This will make the clearcoat lay down flatter.
You could even just apply one more wetcoat of black before clearing if you wanted to.
