Discouraged by my technical deficiencies as an artist, but determined to improve!
You must be BRAVE!
I must deploy aspie perseverance!
Combined with an aspie eye for details.
I had a go at that for a while (a few years, in fact). A friend of mine (who was a professional artist) gave me some really good advice: work exclusively in monochrome at first, so as to focus on the patterns of light and shade, then bring in the colour once you've masterered that (or as near as you can be arsed).
Apart from that, getting your work looked over by a trained artist , on occasion is really, really, really helpful. That saves endless agony trying to work out where you're going wrong for yourself.
