Other old studies I decided to share now, it includes hands drawn from both reference and freehand. I did this study basing on the "100 exercise" of the video "When in Doubt, Draw 100"
At the time, I wasn't going to share my hand studies because I thought there were already a lot of hand studies so much better than mine around DA that I wouldn't be adding anything useful. But as I skimmed through them, I remember great part of them were based on how to hold a rifle (as you guys probably guessed by now, one of my character's main weapon will be a rifle!) and that was something I thought important to keep here in my gallery since it's part of my studies for my future manga. I mixed with common poses too, but in general my hand studies sheet will have mainly hands "holding things" or resting objects over them.
The middle finger was because I was too angry I was drawing like crap that day, ironically the middle finger didn't come out so bad and it was actually freehanded! :'D
----A bit about the 100 exercise---
It may sound obvious that drawing something 100 times will get you good at it, but a lot of us most of the time just try to make a full drawing and then tackle the problem in the way or just fully avoid the problem at all, or just give a small little study on it and think we will be fine (then later get disappointed that your study seemed to not pay off). Well, the 100 exercise is just to give you a certain number that WILL pay off, and honestly it really did. I was no master at drawing hands, but I gain a lot of confidence to the point they weren't scary to draw anymore. So I recommend if you are struggling with something to really do the 100 exercise, but GO UNTIL THE END NON-STOP. Don't tackle other subject neither give up in the middle. I remember when I was in number 40, I was still very disappointed with myself and thinking I wasn't improving at all, but it was only around number 70 that I actually started getting happy with the result, and I actually ended up drawing more than 100 hands during those days because suddenly it went from nightmare to fun!
