Deviantart was my best resource. I learned just about everything from there. One thing everyone needs to learn when the draw though is to draw what you SEE not what you know.
What color is snow? White. What do you see when you look at snow? Pale or deep blues, shades of purple, and with a light on it a bright orange that contrasts nicely with the blue.
Learn to look at things, the darks and the lights, the shadows, the highlights, the colors.

Holy crap I just previewed it and realized I put a toooooon of tuts. Lol. For books I recommend NOT getting those "Learn How to Draw!" books because they basically manufacture the same thing and they don't teach you human anatomy. I suggest going to the library and getting a human anatomy book and look at how the body is made, focusing on bones and muscles. Once you know those positions, you'll be able to draw a human body well.
Oh try to search for a folds tutorial on the first link, that's important! i don't think I put it up there.
Once you learn how to shade (light to darks and so on) and learn the human body, all it really takes is practice practice practice. Just like everything else. Trust me you may HATE what you draw now, but later on you'll see improvement, I guarantee it.
Don't rush off to Micheal's and buy fancy pencils and erasers and such. You honestly DON'T need it. You can go to walmart and get a decent sketchbook there and the good old number two pencil, or a mechanical pencil is just good enough. Get an eraser though, one of those white ones, cause a pencil eraser will run down fast.
Draw everyone and everything. Deviantart is a great asset that shows you amazing techniques. Plus the art...eh ma gad. Its amazing.
Another thing, don't trace. Some people say it helps them, for me I say its a crutch. If you know the proportions of a body you won't need to trace. A head is egg shape. The eyes are in the middle
of the head. Nose halfway from the eyes to the chin. Lips halfway from the nose to the chin. A typical female is usually 5-7 heads tall.
Lol I have more websites and guides but I have to get off. PM me if you want any more advice, and I'll post more here later!
