I'm going to start grinding through my downloaded books today. Should I start with Keys to Drawing or The Natural Way to Draw or some third book? I'll eventually get to whichever one I don't start with but I'm having trouble picking the specific starting point

Anyone who has spent more than an millisecond thinking of or looking at or replying to this thread is ngmi and a faggot.
I don't care if you do or don't draw loli, but you should be spending your time drawing instead of wasting it justifying yourself or demonizing others.

Is it possible to develop eidetic memory?

I'm not talking about memorizing long numbers or order of playing cards - that's useless IRL.
But memorizing faces you see in a bus, so you can use them as a reference later, or landscapes you see and accurately draw them later would be incredibly useful for an artist.

Sadly I can't find anything useful on the Internet. Can you help me? Do you have any tips about improving visual memory?

Do you have any books about making tattoos?

It seems like a fun way of making a living.
