Nice that you got a wonderful cup! Your coffee/water ratio is about the same as mine. You might consider some sort of funnel/filter-holder that will let you brew right into your thermos.
Now that you know you can get a wonderful cup out of this rig, you can play around with the pour technique. The pour is the critical part of the pour-over. John posted a very interesting video a long time ago, but I can't find it.
This guy has an idea I haven't tried yet. Notice he preheats his carafe. He pre-infuses and waits for the bloom, and then adds water in small amounts.

This guy's pour isn't bad, but he neglects to pour a little and let it bloom before continuing. Pour starts ~2:50. No doubt you recognize that Bodum filter.

This guy has a great pour, but think he used too much water for the pre-infusion, otherwise good.
