Hey, i'd like to offer some feedback if that's ok with you
I see you've been putting a lot of effort into drawing all those hands in quantity which is great ! But i would put a little more emphasis on quality when drawing a subject as difficult as hands
It usually helps to focus on using construction to understand the complex structure behind it, it's a big part of what Marc tries to teach in his course early on and allows you to draw them from imagination later on with more practice
With that said, keep up the great work/effort ! Looking forward to seeing your journey
