Some Problems
I'm not in one of those fluid writing moods right now, so I'll just list the things I liked and didn't like in pros and cons:
+ The body proportions weren't perfect, but still looked good
+ The hands look absolutely gorgeous!!
+ The lighting and placement have perfect aesthetics, and the presentation looks spot-on
+ The colors are mostly chosen well and look good together
- Saeko's right breast sticks out too much for the angle she's standing at
- Certain fills such as the sword and hair, only had two colors but should have had a third, brighter color used more sparingly to bring out the lighting and dimensions
- Something about the face seems inauthentic, almost like the art style of some Cartoon Network shows rather than anime. I get that you have your own style, but that's definitely not a Saeko-esque expression. Especially given that she's smiling.
