Congratulations on the maiden, your landing picture tells the story of the bounce. You are in a three point stance, that with 20 degrees or less of flap.
If you ever read Pappy Boyingtons book, specifically the first landing he made at his AVG base he addresses this pretty well. Basically he tried to three point a P-40, in spite of the pilots manual saying “Never three point, Always wheel land this plane”.
The wing flying is what dampens the bounce from the un-dampened oleos, or wires on pavement. I’ve made that mistake a few times and not been as lucky as you.
I hope to get back to the maiden on mine soon.
