I don't know much about ice fishing, other than you dig a hole in the ice.
You probably did not do anything wrong.
90% of people simply cast over the top of the fish they are trying to catch...They put the bait where the fish are not.
If you have not had any bites in 10 to 15 minutes, chances are there are no fish in that spot.
