This is my first critique (to my recollection, at least), so I hope I'm doing it right (xD) and that it is well-received.
This is gorgeous, as is par for the course with your work. It's very captivating, and also elicits fond memories of the "Wet/Dry World" from Super Mario 64 (I'd be surprised if I'm the first person who's thought that). I especially like how the buildings are a little curved. I'm not sure if that's supposed to be because they're underwater, or to give the piece a certain character, or both. But in any case, it works great and is fun to look at, IMO. A couple pieces of constructive criticism: The water texture, although very neat-looking, I feel could look a bit more realistically like water than it actually does. The very thick and tight net of intense lines does not seem realistic as the water seems (judging on its large-scale "shape") to be very *still*. On the other hand, water is *not* an easy thing to portray artificially, I think, and that might go doubly for still water, since you have to show that it's water without making it very intense. The girl is gorgeous, and overall drawn very well in what I would imagine is probably a difficult pose to get right. The solitary thing about her that I can find that doesn't seem quite right to me is that her thumb seems a bit short and does not have much of a joint. But the rest of her anatomy is perfect, and the fact that I was drawn into the details enough to notice that, and that I had to look to that level to find it, says something. It's truly a fantastic piece overall.
Thats probably some of the most amazing water I've ever seen drawn. I love the of this. The water isn't just a hug blue mass with lines. The buildings are structured very nicely. There's a nice tone of shading done to her hair. There's also some real good shading done on her arm and legs. You even went through the trouble of making a painting in the background. I really like the little leaves/lily pads in the bottom right corner. Its a concept and design I've never seen before. Its amazing. As usual, your work is flat out amazing and I am blown away.
This is a gorgeous piece! I love the vibrant colors of the girl's swimsuit and the different shades of the water. This make me think of the Zettai Zetsumei Toshi games, like maybe the aftermath a year later. Anyway, this is very creative and I love it!
The swimsuit girl sure looks nice, but what really catches my eye here is the background. I think I've never seen an underwater background this good before. The different shades of blue you used and how the waves break the sunlight looks great.
