These look marvelous, Technetium. I like how you present them, especially the ones in monochrome. I don't know... they just look really appealing. Do you put artistic filters over these, perchance? They look really vivid/saturated, that's why I'm asking. xD
I did want to mention a tiny thing involving form that was present in one of the pictures, so if you don't mind me giving a teensy bit of feedback... I'll continue. There's actually a good chance you've already noticed this (since, as an artist, I know what over-analyzing is like). But anyways, in this one
picture, the angle at which her left leg is extended doesn't fit the shape of the skirt. Either the hem should hug her leg more, or you should bring the side of her skirt out a tad. It's not really a big deal, just something to consider. You know, just to make the contour flow really well.
Keep up the fantastic work, Techetium. You have (a) pretty distinct style(s), in my onion, so I hope to see more from you.
