Sparklings in primary colors

Since I've known Blaster has two official mentioned siblings, I want to draw him with them together.

Most TF siblings are twins and both are the same gender, and have similar alt. mode. But Blaster's case is extremely rare:He has siblings with different genders! And they do not have the similar alt. modes as him. Therefore, I do not make them as triplets or any two of them as twins.

In my fandom, Toaster is the eldest, then Blaster. Karmen is the youngest sister.In this pic, I draw them as sparklings.
