This is certainly an improvement upon the original Red Tulip Bookmark! I must say I'm thoroughly impressed with the fact that you have managed to maintain the original concept, but remembering to pull back the drama, so to speak. The drama meaning, in the original picture, her pipe smoke was taking entirely too much of the picture. Now, everything (and I mean EVERYTHING) is set in a more sophisticated manner while still being unique and dramatic, but only to a point. I would also like to take note of the fact that your anatomy skills have greatly improved, and your semi-realistic style has gotten more towards the realistic side.
For example, look at her dress. The folds of the dress are beautifully and believably placed. Even the way the dress itself settles on the woman's body is very neatly and realistically done.
The only thing I can say I'd change about this is that it shouldn't be a bookmark at all, I'd rather see it as some sort of wall scroll or a calendar!
This is probably my favorite out of your bookmark series. Normally I would have gravitated toward the black roses piece, but I didn't find that one nearly as sophisticated nor as beguiling as this. That, and I also find that the color red, when used properly, is an alluring and colorful option as opposed to black, which normally strays from vibrant and passionate emotion and borders on emptiness (that's just my opinion; I love black, but red is so much more impacting).
Tulips, in my humble regard, have always been that in-between flower, as though it's trying to be a rose but really failed. I never found tulips to be that beautiful, but here, you took the flower, and turned it into an alluring, sexy, almost underground level, made them filthily gorgeous and filled with temptation.
The way you can only see half the subject's face. The straightness of her bangs. Sketchy, but oh so accurate folds of her elegant dress which sexily covers all but the top of her torso. It's stylish, and elegant. The only thing I wish this piece had more of is contrast, which I know, is not the style you were going for, but for me personally, I would be more draw to it if the colors were bolder, as well as the shadows.
Otherwise, it's exquisite work, and my personal favorite out of your bookmarks. The rest of them, for the most part, are too whimsical for me, unlike this one, which reeks of artistic prowess and recherche lust. Thank you for gracing us with your pieces. You are truly on your way to becoming a master at your craft.
