To be honest your game is still more or less the same as it was. You can still get in and pressure him, and his armour is either easily punished on whiff or broken from the hat setup.
Your spin creates loads of problems because he cannot jump in at all if you have bar, and you can blow up his gaps very easily. I'm no expert on Kotal, but SG is pretty free to pressure, and if you just njk on wakeup, he has limited options for escaping your pressure.
It feels like Every time I start to apply the traditional tempest pressure I get poked out by d1, or when he gets up I get grabbed by that obnoxious command grab. I think it's mostly the fear of the 19% grab that throws me off.
