Within an e-Book, several concepts and stories should be explained by corresponding pictures. (For example, a "before and after"-guy who is nervous first, then confidently smiling . . . and other people in different situations.)
Actually, I´m seeing this as line art / pencil drawing in black and white, but I am open to suggestions.
This won´t be whole pages as seen within a comic book, but single panels / pictures which will filled in within the text.
I am not looking for extremely detailed stuff (like exact shadows, etc.). An overall picture with just line art might work perfectly. But, as stated, I´m here open for suggestions, too.
However, the pictures/situations need to explain themselves, so it is important that you are able to draw recognizable facial expressions and movement within a scene.
Please state an estimated price range per panel. It would be great if you have examples where you can mention a price for, so I can get an even better understanding.
Thanks a lot in advance!
