That looks good. Though, you may want a swap partition - or to use a swap file. I'm entirely unfamiliar with Parrot - so maybe someone else will be able to offer some insight. I've booted to the Parrot image just a few times and only to test something.
I too often partition /home as its own partition so that I can easily migrate, though it's easier to just let (most) installers do the work with a single partition.
Some folks say that swap isn't really required with an SSD, but I still make sure to at least use a swap file. Swap isn't just 'space where we stuff things when we run out of real RAM'. It's quite a bit more complicated than that.
