Post draft panic

I had my final draft tonight. We do standard ESPN keeper rules for two keepers and I kept none. I had the 12th pick of 12 and because I had no keepers had 24, 36, and 37 as my next picks.
Just looking for general suggestions (I know it’s tough in a vacuum) to try to improve my post draft roster. (12 team .5 ppr)

Any and all thoughts/tips appreciated.
