Hello there,
I saw your illustration book idea, and without a second thought, I would love to work on it. Yes, I have worked before on the illustrations for children. But I have stayed in the realm of the drawing figures and environments more.
I would love to work with you, and if you want I can send you some examples of the illustrations too, later in chat if you are interested.
We will be starting off with your script, and you can approve the script on the rough sketches, they will be really rough to get the positions down for the characters. When you are satisfied, we will move onto the phase, of cleaning up those sketches and applying the feedback.
And when these are approved too, hopefully, the last phase of digitally rendering and cleaning them up will come and will keep polishing them until you are satisfied.
You will be satisfied, and get more than your money's worth. That's a given. Anyways enough of my confidence showoff, hoping to hear back from you.
