AWESOME PIXEL ART / SPRITING TUTORIALS, ANYONE?

I would very much like to learn how to make my own sprites / tilesets. And to this end, I am looking for awesome tutorials to help me with this. I was hoping the people here might know some.

However, please take note that I'm really looking for tutorials that take me by the hand and explain everything well, and are focused on spriting for games. I'm a complete beginner when it comes to this.

I've also read about the basic concepts of lineart pixeling, shading, light source, dithering, etc. But even though these concepts are important in spriting, even if I know them I still can't make my own sprites. So tutorials that just explain these concepts are not something I'm really looking for, as I already studied those.

Gonna bump this, because frankly there is still one thing I haven't found yet. There are quite a number of pixel art tutorials that try to explain creating a grass tile, but not many of them do a good job.

Is there any tutorial that actually explains me what to do? And not one where it says "use multiple shades of green" and then shows an image of a perfect 16x16 grass tile with varying blades?
