@sumit_makwana I see, Keys to drawing is a great book for observational and to draw from imagination. I think it’s a good book to begin with for drawing, however later on you should look into The Vilppu Manual of drawing which deals with the human figure from a method that he implemented (and most animators follow nowadays) to draw the human figure.
Regarding animation. Please DON’T purchase every book there is about animation just yet. Purchase one or two and study them thoroughly until you’ve mastered their contents before jumping to the next. At this moment in time, I’d suggest getting Preston Blair’s book and Richard William’s book. If money is of essence Survival Kit is the way to go.
The first one is geared towards drawing for animation, particularly construction drawing for cartoons, but this knowledge is applicable to all drawing styles that are used for animation, everywhere, believe it or not. The second half of the book leans towards understanding core principles of animation from a hands-on perspective, from rythm to gesture to timing, dialogue and more.
The Animated Survival Kit, is a great book but is not as “introductory” as one might want. You have to read it with utmost concentration particularly because the basic steps and methods are implied within the first 60 pages (along with some attempt of Disney’s history of animation and motivational speeches). The working method outlined in that book is the one that most animators use today, either having a traditional or CGI approach. The rest of the book is about how to create all types of walks, which will allow you to understand many of the principles of animation through a hands-on approach as well.
The complete animation course from Aaron Blaise has a great review of the principles of animation, however I think it makes some assumptions on the viewer’s knowledge of animation, so to me, you’d still have to kind of know already what these principles are before watching those videos so the knowledge can thoroughly “sink” in your system. The strength of that course is that it allows you to watch him animate a walk, a run and his approach to dialogue scene, which truthfully almost no other animator exemplifies. Ever.
If you’re short on cash I’d suggest first watching these introductory videos to the principles of animation by Alan Becker, which, in my opinion, completely solve the need for understanding them,
In order to squeeze the book’s potential I suggest you have a look at these other videos in youtube.
Please Watch this TED explanation on Timing & Spacing.
Also Watch this explanation on keyframes, breakdowns & inbetweens by Richar William’s son, Alexander Williams, who’s an animator in his own right.
Also watch this 30 minute lecture from Animation Powerhouse on Timing & Spacing
With this working through the book will be much more satisfying than just jumping right in.
