Colored sketch gift for a Zoroark friend! His left hand took forever for me to get looking something like correct aughhh! But practice is practice.
I'm considering offering the same kind of half-body sketch for free soon, as long as what's asked for isn't too outrageously complex. Let me know if you'd be interested. Just don't expect it to be done too fast, considering the time of year, and I'd be working on it parallel to my day job and a new refsheet for my fursona.
Hands are the worst.
You have to practice, practice and practice again ... Like, i mostly took a pic of my hand, in the position/pose i wanted to draw and first tried to get that right doing lots of quick sketches, before continuing the draw the hand on my drawing.
I think you are already doing pretty good.
Don't ever stop drawing. I did stop a long time ago and haven't been able to get back into it.
