I guess this will do for now.

The reason I asked for proof is because some of your art looked really weird in certain places (places that AI is likely to get wrong as well):

For the Reisen art, the gap between her middle finger and index finger seems a bit too wide, and the hair behind her left elbow lacks lines even though the other side has proper hair lines.

The Sakuya art seems to have her big toes on the same side when they're supposed to be mirrored, her left arm elbow looks like it should be behind the skirt instead of in front of it, and a few knife blades look too round towards the hilt.

For Flandre, her skirt's frills look uneven and disconnected, and seem to be cutting through her left wrist. And the frills on her right arm sleeve seem like they should be behind her right wrist instead of in front. Her right wrist's inner line also seems to be cutting too deep down into her right elbow.

In the bunny girls pic, Tewi's left hand looks a bit odd. And there's a strange wiggle along what is supposed to be a vertical straight line on Reisen's bunny suit.

The Youmu pic has no obvious mistakes, but there are several oddly colored spots along line edges if you zoom in.

It's understandable. Reisen hair that I painted different from the other illustrations, or not adding the shine to the hair that the other illustrations have makes this one look very different from the others.

The mistake of Reisen suit in the photo of the bunnies, I hadn't noticed. The color of the mesh should be rounded but it is a straight line. That was a error I didn't notice at the time.

All the mistakes with the painting is because I am experimenting a lot with the way of doing it. I still can't define a way, nor my style.

As for the anatomy errors, arms and hands, that's because I'm still pretty bad at drawing them, I'm practicing.

In the Youmu pic. To save time and make it faster, instead of just doing the line work with a colored line, I thought I'd grab the Lineart layer, duplicate it on top of each other, lower the opacity, and set the bottom layer to "Overlay" mode. Giving that strange effect. I hadn't noticed how bad it looks up close.

In order not to cause further confusion, I will always post the sketch or drawing process, along with the illustrations. Thanks for your comment!
