Cactus / red flowering hanazono kabuto

The photo is a grafted 2nd filial red flowering hanazono kabuto.
It is (hanazono kabuto x red flowering aserias) x red flowering asterias.
Since the flower of 1st filial was not red enough, I crossed red flowering asterias again.
It seems the flower is now red enough.
The scion is still very young, 1 year old and the character of hanazon has not appeared yet.
