That is quite interesting. In general when I start to draw I often find myself limited with what I'd call “lack of imagination”. Letting yourself go alongside is something I admire very much. That I envy a little too, to be honest . Really well done, by the way!
Well, in my opinion, you shouldn't "think" too much when you start your work. That drawing period, when everything is rough and messy, is when you need to be completely relaxed and not focused at anything, especially not at background story, idea or details. At least that's how I do it, it may not work for everyone, but after I'm relaxed like that, having no idea what I'm doing, ideas start flowing in, and that's when I start focusing on adding details and solving all kinds of technical artistic problems (:
I think I won't thank you enough for hat you've just written. If I could frame your words of wisdom I would for they indeed sound very true. You're right being relaxed is key — now you've said that I remember having read it a few times. While you're busy thinking you're not letting your creativity go . Thank you very much again for sharing!
