I second
>>5876172 here. It has confidence, like something you enjoyed drawing a lot more. You also exhibited more visually interesting color choices too compared to the others.
>>5875704>>5875706>>5875708These pictures seem kinda noisy:Tthe values and colors are harsh and plain, always getting deep darks and reds, and your focal points are compositionally a little lost. I would look into mellowing out on both your inclusion of details like the hair strands, as well as your shadow values and keeping contrast only on areas you want eyes on, as well as looking a little more into color theory and playing with combinations outside of your comfort zone, as it kinda looks like you do everything in two color tones with one darker than the other and no hue variations.
I think another thing is that in the original she barely really has any emotion, so I cheated with the lasso tool to curve her lips slightly into a smile I'd expect from a Gyaru, giving her some generic hearts to tell the viewer "hey I'm enjoying this a lot", and splattering more seed on her chest since it felt a little too clean for someone cumming all over the place. Add in some breath/horny steam and fog/filter out the background since it's less important and I feel like things FEEL as much more lurid as they are literally. You should do more for eye's expressivenes too (window into soul etc etc)...
The other anon pointed out anatomy and he might have a point, though I think it can be forgiven if the other things are adjusted. I lasso'd minor things anyways, and maybe you can use less harsh lines on overlapping figures to like the other anon said: those boobs don't look so paper-like when bending. With a soft fleshy thing like a boob it's better to imply plane changes with values than hard lines.
Overall, these do look like the opposite of confident, more like you just don't want to draw them at all and fell into a habit that lacks experimentation (I'm totally projecting here too, though.)
