I am really hopeful that you meant 2000 grit and 3000 grit?
But looking at those scratches, it does not appear to be the case.
You have used way too severe of sand paper for automotive finishing applications. The correct approach would have been to use something between 1000-3000 grit to remove a clear coat scratch.
2000-3000 grit paper leaves fine enough sanding marks that can easily be removed by machine compounding and polishing.
You're quite lucky you did not strike through your clear coat if you did in fact use 200 and 300 grit paper. You will need to continue sanding (and hoping you have enough clear coat left), working your way up to 2000-3000 grit before compounding.
