I would advise against breeding him. He is very poor quality imo. His face is too small and thin, his tail is too high. He is not hard feathered in the least. His legs are too short and thin.
All I am seeing in your male is a non-picked-out tail. I breed my Thai males for tails that are about as long as they are. My male recently lost his sickles so I can't show you. When he grows em' back I'll let you know.
Here is a pic of a longtailed asil (not my pic):
