*cough* *whisper* that isn't really constructive, so I can see why it would be hurtful *cough* anyway!

Here are some pieces of advice;
1. Don't TRY and draw in a style. You're style will be something that comes naturally, if its something you have to force, or try at, it isn't YOURS.

2. Tutorials are great for learning how to draw the basics of something, but don't assume that the person creating the tutorial is a master and never makes mistakes. The best way to learn to draw something (in your case, humans) is to draw them...a lot...like, crazy lots lol Tutorials can be helpful, but experimentation and drawing from models is 100% better.

3. (this last point is more personal opinion and observations than anything, so disregard it if you wish ) Learning realism before learning how to draw stylized humans is LOADS easier. I started to draw humans after watching anime...which we allll know can be about as unrealistic as it gets! Now I'm stuck with habits that I've developed because I never bothered to learned the basics about the human body. I used a style as a crutch because I was lazy. You'll be helping yourself in the long run if you at least familiarize yourself with the basics of anatomy before getting too heavily into cartoon styles.

*shifty eyes* That was longer than intended, and perhaps a bit preachy. Sorry 'bout that! :S

Thanks for the great advice guys. <3
