Last image is finished! I can open the next batch, woop woop!
So yeah, Taylor, sorry it took so long. It's been a week or something :u
I had a few challenges with posing and trying to express their personality only in shape and appearance. Emilia doesn't exactly look much larger, but she's distinguishably more bulked than her sister. Olga's tail was hard to replicate, so the markings aren't spot-on. I chose out a playful chasing scene because why not 
Even with these difficulties, I managed to finish them just yesterday on the 31st of May. Do say, I like their choice of colors, it blends a little and it contrasts, but overall works out. Olga's squiggles don't seem to be evenly distributed, but I think that would make sense, knowing how dense the scattering would look. Hope it's worth your time!

If you would like anything changed, or if I made a mistake somewhere, please tell. Oh, and for those who would like to request, this week and the next, I will have my final exams for this year, which doesn't stop me from drawing, but it's just to say that I may be occupied for the moment. Thank you!
They look amazing, thank you!
I understand that Olgas markings can be a nightmare, so as long as she has squiggles on her tail I wasn't too fussed.
Your art is amazing however!
