Hi and welcome to Polycount,
For traditional learning go for;
Bridgeman's work and 'The skilful huntsman' Both on Amazon.
Daily practice exercises~
Its a how to guide to starting off concepts.
Figure and gesture drawing
Real life drawing exercises. Brill for shading forms and stuff
Similar to the one above but it uses 3D models so you can see the muscle structures and stuff. Again stupidly handy.
If anything else comes to mind ill throw it up but to be honest it'll come down to how much your willing to actually work for it. Good luck!
