And there's nothing wrong with tinkering with older works, to want to improve them.
But sometimes, one can tinker too much, or the current technology\ability / skills doesn't mesh well with the older style.
I've been going through some of my works lately, and wondering what I could redo, touch-up or what I should just leave alone. The Death Beckoning I should have left alone, and when I went to redo it, I was happier with the original.
With this, the Alseid, a woodland nymph of mythology who lured men into the forests to devour them, souls and all, I originally tried a few techniques that seemed to have worked. Yet I was never really satisfied with it - I like it enough I'm planning on making a print of it, but I thought I'd try touching up a few spots that always drew my eye to and I wanted to fix.
So here's the original, with the touched-up version below.
