I'll be interested to know how you get on, NanKate!
I was painfully useless at art at school - used to dread it and really envy girls who could draw ponies (that looked like ponies!) all over their rough books. I couldn't draw a lifelike pony to save my life. And still couldn't to save my little Gdcs!
I've had people insist that I could learn if I put my mind to to it (never mind the art teacher who evidently thought I just wasn't trying) , but not like that, out of my head, I couldn't, though I might be able to manage a just-about passable still life of something right in front of me.
To me it's like telling someone tone deaf that they could sing in tune if they really tried.
One thing I did always want to do, was take up the piano again. Having passed grade 2 at the age of 10 and barely touched a piano since, I virtually had to start again from scratch after I retired.
That was some years ago - I'm now playing grade 5/6 level,pieces, and my latest challenge is Chopin's Nocturne in E Flat major, which has been set for grade 7 so daunting, but not too dreadfully so.
When I started again I never even dreamt of getting anything like this far, so I do hope you find the same with your drawing!
