There is nothing wrong with the tutorial itself, I actually like it because it's well written and has a good use of images which makes it very easy to follow even without reading. Very good work indeed.
The sprite is, on the other hand, not too good. Don't worry though, you're still new to spriting, and some practise is really all you need, just like the rest of us

I can't help but giving you some critique on the sprite itself, because I love sitting around and trying to help others to improve while doing nothing myself :P
Your basic shape and anatomy on the sprite is pretty good, even if you could make the contours and different colour less "slimy" by using a smaller brush to give it some edges. The shading is a bit too smooth for LF2 style, but yeah, that's LF2 style ;P
Also, try giving the sprite's clothing some folds and move the highlight on the very right of the sprite more to the left, because the sun doesn't really shine LF2 characters from beside/behind.
Ehr yeah, I can only quote Lauli here:
Lauli Wrote:Nice tutorial!
I would like to see more sprites from you.
You might improve even more!
;D
So yeah, I'll look forward to see more tutorials from you because I like your style, and see you around ;P
