Congrats making it to round 4. Good luck to you. I've seen Kor-Rune's stuff, and I confirm it's huge. Looking at the professionals always makes you feel insecure, but never mind that. Just use what you've got and do your best with it. keep the basics in mind. Variety, constant rhythm, not too hard not to soft, work steadily towards the climax. I'm sure you'll perform well.
