Black Rose Butterflies

I was practicing drawing a rose and I thought, this cant be left alone, it looks lonely. SO-oo, I drew two butterflies. I call the one on the left (female) Jeni and the one on the rigth (male) Zack. ^^ Zack is my OC and Jeni is my sis's.
She has a DevArt thing too:

I named them jeni and zack because the butterflies remind me of them. Wanna know why? Becuz Zack is originally ebil but when he met Jeni the newborn, he started changing, though is still scary and ebil, he doesnt hurt her and wouldnt hurt anyone she doesnt want him to. Aw, aint that cute
