You're willing to put a lot of time into your work which is a good sign.
Right now it's very sloppy, if you want to go further with this style you need tons and tons more rigor to your linework.
>>97>>100the way your lines round up at the end is just ugly, when you crosshatch like this make a line, finish it, lift your arm and go back, always crosshatch the particular patch from one direction only to another. What you're now doing has the quality of a bored schoolboy scribbles. I know you want to finish it and it feels good, but cross hatch 5 times slower than you're already doing. The eye follows the line, if the line is constantly bouncing left to right to left to right the eye gets confused and your linework has zero flow.
My suggestion is train the mechanic quality of your lines without making actual compositions, just fill pages upon pages with lines that go in one direction. The way you do it is you put 2 dots and try to connect them with one line, one movement. You can and will have to 'ghost', move your arm back and forth over the paper and when you're comfortable, 'drop' the line where it should be. If you fail, don't go over it, make another pair of points, and try again.
For artwork study values, you're getting there,
>>100 looks actually very nice as a thumbnail, but for example
>>101 the figure is absolutely lost on the backdrop of trees.
Research atmospheric perspective. Your stuff lacks depth at the moment.
>>97the neck from the profile is wrong. In a neutral position the neck comes out of the torso at an angle. Acquire and study Atlas of Human Anatomy for the Artist by Stephen Rogers Peck.
I'm envious of your meticulousness, if you learn more about painting and employ that knowledge to your art you will kick ass.
