Very neat and beautifully grown! Looks most likely to be a typical x "Red"?
The F2 generation of plants from self-pollination may produce a wide variety of offspring, and it may even get cross-pollinated again by the D. 'Albino's' or others to make even other variations.
Regardless, there should be some nice big genes in the offspring and I'll love to see what they look like
Maybe even try manually crossing the big ones and see if you can get any bigger
