Thanks very much! Thanks everyone for their feedback!
...Have Marco get a haircut later in the series like he does in the books.
Thy will be done!
We are just so used to picturing Marco with short hair, we forget he started with a longish hairstyle. Hehehe.
With Tobias, I reckon, to discern the character from Jake, his hair needs to be the dirty-blonde and short, pure and simple. Even in the models, I am sure I wasn't the only one who thought so. The model Cassie never had sported her hair the way I drew her here.
Scratching the look of the book models, I am attempting to create my own 'look' to the characters for the novel.
