Oh gosh, thank you so much, I’m glad you enjoy my hands and noses! I don’t think I am anywhere near qualified to make any kind of a tutorial as I don’t think I’m too competent at either of these features, HOWEVER! Here’s some relationship guides I have come into the habit of using, especially if a drawing is giving me trouble!
For the noses, I start with the perspective of the brow, and from there, try to figure out what shape and angle the nose would be seen from? That’s a really helpful starting point for me! I find that laying down a few spacial clues gives me a better idea of where the nose belongs.
With hands, if I feel like I’m losing the form or I don’t understand how the fingers would look in perspective, I try to start over simple and imagine the hand as basic shapes. This usually helps me get a little more organized and in a better place to start fleshing out the features. (If all else fails, you can always look at your own hands!)
TL;DR I’m not sure what I’m doing but this stuff seems to help me!
I hope this is okay! Thanks so much again!
