You would think books would be really easy to draw. They're just rectangles and boxes. Aren't they?
I suppose it depends on how accurately you want to represent those shapes.
There are a lot of straight lines on books. Straight lines are hard to draw without a ruler. Then again, as you can see below not all of the lines are absolutely straight. If I used a ruler it might help but I am sure it would look stilted and robot like - which is not what I am going for.
The books I have represented below were sitting on the coffee table in the living room. I thought I would actually try to observe what a book actually looks like. I decided here not to concentrate on the text and graphics on the cover. In the limited time I gave myself to draw this. I tried to represent them as accurately as possible.
The following dimensions were things I discovered in the drawing of books on coffee table.
1. Text and graphics in cover - blurred because text is difficult to represent in limited time and I wasn't sure how to do that.
2. Straight lines - difficult with free hand drawing - lines can get wobbly
3. Perspective - Single point perspective - I don't think I paid enough attention to vanishing points but tried to take it into account.
4. Tone - light and dark
5. Pages - How do you represent pages between the covers of the book? I tried to use multiple lines.
6. Shadows - The books are kind of floating because there is no shadow grounding them.
The end result, i think, can be recognized as books stacked. In my opinion, a good book is more easily read than drawn. More time might help.
I'll keep on practicing and trying to make little improvements here and there.
