I'm sure you'll get feedback on the drawings themselves. I wanted to mention your setup or lack thereof. If you're sitting on the floor/bean bag type posture, not only are you destroying your drawings but also your spine. A drawing board, good setup (bench/tabletop/standing easel/2 chair setup, or 1 chair-1 table), good lighting go a long way, and some of them without breaking the bank. It is worth mentioning that working that close and that small doesn't allow the shoulder to make marks, rather the wrist. Stan has a video on this. So I would also urge you to work at a good distance from your board. If you are buying a larger paper, make sure the board is the right size. It is also worth mentioning that the drawings need to be photographed better to judge proportion because of the page distortion and unclear reference (I can't tell which drawing is which pose).

You did a good job with not getting into details. That being said, look at the middle photo (model) and how it's basically falling to our right. I don't feel that falling/draping in your drawing. Connect the public bone to the pit of the neck with a straight line and compare the drawing with the model to see what I mean.

I think it's worth mentioning a few things that maybe haven't been said. It's not a foolish question. Art IS subjective, so success isn't simply dependant on skill/talent. There are many unemployed artists who are more skilled than SOME of their employed counterparts. Sometimes it comes down to knowing the right people, being in the right place at the right time, and sometimes the tides of fashion just change to a particular style/medium. Since you don't control those elements of luck beyond a point, the general advice is, a) do what interests you and b) do it well. Both those things are much harder than what most beginners think. In the normal world people can take 4 years to follow a prepaved path and become an accountant or lawyer, say. Art training is different. It takes MUCH longer than anyone (even art teachers) will admit to do the most basic things (like drawing a straight line). I'm not saying lower your expectations necessarily, since you could always get lucky even without being the most experienced (see above). Mad skillz, again, do not guarantee success, but may not be necessary perhaps because luck (big emphasis on the perhaps). If you still want skill (to increase your chances), yeah, lower your expectations or be born talented. It's not like a normal degree/field of study where it takes X courses and Y years and BAM now you are an ISO certified artist, step right this way for a job.

Seperate the lights from the darks more.
