Art tutor for 12 and under

I have an A in GCSE art and I have recently finished an extra art course is drawing and learning how eyes work in art creativity.
I would be using pencil as a a start off where they get the understanding of basic outlining of drawing.
Colour and if wanted paint would then be introduced to understanding the blend of art.
Each child see art and colour differently so it would all depend on the quality the mind has been set.
