As for illustrations, they can be in colour, or line drawings.
In the case of line drawings, you (or your children) can colour them in, as you see fit.
Colour illustrations are done with watercolour, coloured pencil ou gouache, and in some cases the results will be enhanced with the help of technology.
On the whole, my illustrations revolve around children and childhood themes, and can be customised for birthdays, alphabets, parties, wedding announcements, and so on.
Again, scenarios involving your children can be invented. Everything is customised to order.
I also produce illustrations for books.
