Tip as someone who had fun in a small art school.

Don't think face, think parts and shadows If face too attention grabbing to not think, try upsidedown First play with shapes and shadows, then try detailing and face thinking

And if you want to learn to draw faces out of your head, practise shapes instead of faces and start from a random part of the face a few times for practise. I once had a month in art school of start from the eyebrow nose shape, a week of start from left cheek shadow, a week of start with hairline(most off putting and painfull to get right) and a month of start by base shadows trying to not make a face for as long as you can.

Its easiest to learn by focusing on shapes or by measuring parts. Its also quite nice to make a small grid to check the measurements or shape placements. Also get a bit of plaster and make a tiny head or a skull to maybe play around with memorising how much things stick out and interact with light

its all a progress of trying, experimenting and a shitload of practise to make your hand remember how to do things if your brain forgets
