GIANT FILE AHOY!
I intended for this to be a process of my painting
[link], but then I forgot to take screenshots, and it all went downhill from there. :C
I really should follow my own advice sometimes XD
Another thing I was meaning to add to this, as you are drawing, be sure that you are constantly zooming out from your picture, just so that you are getting an overview of your process. It is harder to spot mistakes when you are zoomed in the whole time, so keep zooming out so that you can catch these mistakes early on!
Also, a more in-depth explanation of why you need to learn realistic proportions before you start cartooning/anime:
Learning how to draw from anime does not teach you the structure of the human figure. What you're seeing on the screen is a bunch of lines that are symbols of the figure, ie the eyes, nose, etc., but not necessarily the real thing. Whether you are a mangaka, an abstract artist, a realistic painter, etc., you are still drawing an interpretation of the same human form, which is a 3D figure that you must learn to translate as a 2D image.
Besides, if you are just copying one style of cartooning, you are seriously limiting yourself. You will get a warped perception of what a human figure looks like, and that's not good. Besides, chances are, if you are a cartooning, you will probably be asked to draw in various styles, not just one. That's why you need to learn how to draw a realistic figure! So that you have an idea of what something looks like, which allows you to come up with thousands of combinations on what parts to exaggerate and stylize. But stylizing something that already has been stylized just doesn't work.
I know learning realism probably won't be as fun as drawing shiny animu, but it is important. Being an artist isn't easy, and there most certainly isn't any cutting corners. So I highly urge you to take a little break and learn some proper anatomy. Seriously, if art were so easy, I'd already be working for Blizzard and making a million dollars. But I'm not

Besides, if you are ever applying for a position as an artist for, say, Disney, or any gaming/animation studio, you WILL be expected to present a sketchbook, full of life drawings and whatnot. So you REALLY cannot weasel your way out of that!
For this tutorial I'm using Photoshop CS5, with a Wacom Bamboo tablet. Using all default brushes.
any questions please ask!
You truly are fantastic at what you do
