How can everyone start with lineart like that, and end with a masterpiece? I start with a lineart like taht, too... then I get blasted to bits by the darned coloring QQ

First off, doing clean line work isn't all that easy...ok its pretty easy, but its not like anyone can do it, so give people that can draw a clean, anatomically correct outline some credit. 

That said, I like to think that it's not so much how clean your lines are, but how clearly you can outline your vision. 

Anyone can trace an animal or put together some clean line work, but if you don't know how to fill it out it doesn't really matter. 

Just practice layering your colors an shadows and you'll get the hang of it eventually. 

Its just like legos.
