First I should have said that I haven't had much training in art. My comments are mostly coming from being a potential consumer of the product.
Oh, I didn't realize it was going to be smaller. What will be the final size? That makes a big difference sometimes.
opinions in regards to what it's right now,
I like the choice of colors. Not sure if "right or wrong", but as a consumer, the colors seem good. Also, the soup, or the contents of the pot looks good. I like the general posture of the wizard, with the staff - all except for leaning a little bit.
After some more looking, I can see that the leaning a little bit can almost give the impression of movement - like if he's leaning over when the stirring stick is around on that side, and that maybe when the stirring stick is around the other side, he leans the other way a little bit. Like if he's moving his whole body in the direction of the stirring action (maybe almost like a dance?).
I think a little more depth in the face might help that. Maybe because the face seems flat, it emphasizes the leaning somehow. Yeah, I'm having a feeling that if the face had some depth details, like the robe, the leaning might seem more natural.`
I was only thinking of "packaging" when I made my first comments. But now I notice in the title, you mentioned "book illustration", and you mention "Breatgne". Is that the name of a book? Or is that how you spell "wizard" or "Merlin" in French? I only know a couple of French words.
Oh well, anyway, I still think it's a nice drawing over all. Just mentioned those things because you asked. Nice work, even with no changes
