Lol u only have 1 pix of the mom who u have raised from hatchling to motherhood? she's a Hypo Black Pastel, there's no need to doubt the breeder if she/he is reputable. u don't need to drive yourself crazy or complicate things. i still think they're Hypo Black Pewters.

that said being that Black Pastel and Cinny are allelic, i have noticed some differences in their respective combos. in my experience for example, a Banana Black Pastel's pattern is more yellow whereas a Banana Cinny is more orange. also a Super Black Pastel is more clean while a Super Cinny alotta times have orange splotching. so i guess u can try for these combo's next and see what colors and patterns develop.
