It's the same for the two other ones, really. I can post progress shots. When I look at stuff like this it's always first 2-3 pictures "yeah yeah I can do this" then "wait, how, what did I miss?"

Edit: mistakes to watch out for:
- Working locally instead of globally - "It's all in the details" - no, it's not. Details are friggin' useless without the big shapes. Details are your enemy, and can kill your forms. Enable the Navigator menu so you always have a small view of your drawing to look at.
- Not using a large brush. Also; no longer using a large brush once feeling comfortable with your rough. This might result in a spotty, incoherent image with nice details. SOLUTION: Return often to the large, transparent brush and knock things back with a wash of colour. It is quick, and works magical wonders. This fact takes time to accept.
- disable brush size by pen pressure in the brush settings. Enable opacity or flow by pressure. A brush that changes size is harder to blend with (but great to ink with), I had to accept that despite my own protests.
- Your digital tools the fill bucket, gradient tool and lasso/move tool can become your best friends here, with much more uses than CTRL+Z.
- Don't panic if you can't manage to render a section of your image perfectly within reasonable time. If this is a problem, choose one area that you can render nicely, and make it the focal point of the image. For instance, I skipped pretty lightly over most of the parsley's frills, but put more effort into some of them to sell the idea.

Questions? :)
