Here some books for the ones that think "I can`t draw" :
Perspective made easy - Ernest Norling
http://books.google.ro/books/about/Perspective_Made_Easy.htm l?id=i0mdk7FvSzIC&redir_esc=y
Fundamental book for design.
It can be complemented with Andrew Loomis - Fun with a pencil

... it takes 6 - 12 month to learn the basic drawing ability you need to be creative
@MrNibbles Nature it is "Public Domain" , works dated 100+ years are Public Domain , works of art 100+ years are Public Domain. You can use old books and stuff to inspire you , just not use 21 century works and not early 20
NOTE: ALL DATED +100 years from the DEATH OF AUTHOR
Like
http://en.wikipedia.org/wiki/Leonardo_da_Vinci ... you get the idea ?
Copyright it is not forever , it is meant to protect the children of the author to have a income after parent death , and to give the author an income ... some author become known after death yet children got income the rights on the works ...
And expired patents.
So there it is not like there it is no way to make it legal , the option it is and it is no hard , to look in Human History. The problem it is combining 5-7-10 ideas in ONE to make an Original Product. Heh.... But that it is why you ask a price on it ? It is research work 98% , 1% drawing ,1% 3D modelling.
Why people see Copyright negative ? It is not!
Stealing it is negative and hurts the income of the employee and the author and hurts the economy in long run.
Example : If a singer publish an album , and he has no sale , that means he can`t afford to hire a "dancer girl" or "more" , that means no job for a girl that has no ability to do more than that , that means the artist has low income and low popularity , and that means artist quits doing what it is good at.
Not all musicians become rich , but yet at minimum success they can hire some like 3 people .... now due copyright stealing they can`t hire none.
The real motive behind ACTA and other papers.
