I've done a good bit of tailwheel flying, and I'm er.. no stranger to the crosswind..
First off, we're looking at a 10kt crosswind component here. That is quite a lot and it may be not
that far off the limit for this particular aircraft. On the face of it, it looks like you are doing all the right things - A wing down approach will naturally leave the controls in the right place i.e. into wind aileron and opposite rudder. As speed decreases there will be a point when a bit of brake can often be needed. That's kind of 'how it is'!
Sounds like you are doing OK to me. I guess its all a question of anticipating what's going to happen. You will find many pilots don't even realize they are feeding in a little brake....
I once had an aircraft with a castoring tailwheel and no brakes... I learned all about ground looping from that! (a skid sorted it out in the end)
