When you are drawing, start inside out.
Gesture sketches and stick figures are a good start here. Then you overlay basic shapes (circles, ovals, etc.) on top to block out the segments of the figure being drawn, and begin working on details from there.
Quick examples of good stick figures:
Those may be just stick figures, but notice how expressive they are? You can visualize an entire, finished drawing out of either of them.
I'm also trying to hunt up tutorials that show the use of stick figures and basic shapes to construct a figure -- ignore the finished result and focus your attention on the early steps:
Obviously, most anatomy tutorials you'll find deal with human subject matter. If you prefer drawing anthros and animals (hey, so do I!), well, the same methods for drawing human shapes work equally as well with animal shapes! Same All you do is tweak how they're placed next to each other:
Again, don't concern yourself with what the finished result will look like so much as focus on those initial steps
, circles and lines that hold the figure together. These are the 'skeleton' (almost literally) of your figure.
Blotch's sketch tutorial. The tutorial itself looks like just any other, right? But the dissertation he wrote to accompany it is to die for.
All I can stress is practice! Work from life, from photos, or from the alien broadcasts in your brain, but all I can say is: Sketch!
Going "from point A to B", studying how to produce one specific result isn't the point of a tutorial, it's not the "how" you need to learn but the "WHY". You won't get that from a book or tutorial, you have to learn it kinesthetically -- "by doing".
After all, chop the L off of 'learn' and what does that leave you? Earn. In order to sketch well you have to go out there and "earn" it, you have to practice and work for it.
