I love this! Each one is so well drawn, and brilliantly designed. Keep up the good work!
As with most people I am going to have to break up that gif up to look at each one more carefully heh. I was a little confused by the love and sin bars, I was wondering if they were going to be the "stats" of each monster but I dont think they move it all, felt like that might have been a bit of a missed opportunity but I guess they are the "players" stats? But hey, that is not the focus of the picture and all the girls are 10/10, great work!
Furries, large tails, and even a long dress. 
i think the "love" and "sin" meters changing would've been a nice touch to this piece, but besides that, it's awesome! i loves.
Really Awsama work: I have a few comments regarding the nature of this drawing but I wont go there
On one particular one I thought you had drawn my OC, Fleja haha
Overall the designs for all these characters look pretty cool, and I can only imagine how much effort they must have taken
Great work!
kudos!
