First off, your drawings are phenomenal! Really stunning for the time frames of each (I assume that's what the numbers mean, the minutes spent on each). Secondly, I am not a native English speaker, and it is late, so I hope my meaning comes across clearly. Also, please keep in mind that this is only my opinion, and your art need only meet you own standard. Nobody else's.

That said, let's start the critique. I'll break my response into two: lines and perspective.

Lines: Specifically, your line's thickness and strength. Let's look at your top left drawing. When I look at it, my eyes are immediately drawn to where the lines are the thinkest and darkest: her hands and face. In addition, your lines are lightest on her legs, drawing the eyes away from them. Now, when I look at the reference picture for that, I see it differently. In my opinion, the hip and shoulder closest the the camera is most accentuated, and the back leg and hands are least relevant to the pose. This is, again, only my opinion, but I will put it out there for thought.

I would recommend using thinker lines in areas you want to bring the viewer's attention to, and softer lines in other areas. Use an eraser if needed, but it aught not to be.

Perspective: Specifically, foreshortening and viewpoint. Let's bring the attention to your bottom left drawing. It is a wonderful drawing, but it does not line up with the reference photo. In your drawing, is seems that the camera has taken the picture from a higher vintage point (for instance the hands, which is hidden in the picture yet shown in your drawing. As well as the knees, which is shown closer to the stomach than your drawing). Now, this isn't a bad thing. It can be a wonderful skill, to look at a picture and change perspective, if done intentionally. However, that doesn't seem to be the case here.

As a beginner artist myself, I have no advice exept to keep practicing. Take note of the negative space (the space around your subject, like the knees and stomach) and keep it in mind when drawing.

Overall though, it is well done for gesture drawings, and most of them easily convey what the subject is doing and where the line of action is.

Keep practicing. You're already well on your way to mastery.
