Leonardo de Vinci might say to start at the margin and not in the middle of the paper, have neater hand writing , try to not go below the lane, and make the words look like actual words. He would probably tell me to work on "S" and my "A" and maybe even my "M" and "N".
It might seem natural to him because maybe he is use to writing backwards or reading backwards. He might not have learned how to write so he might have taught himself or maybe because he was left-handed and he thought that because he was left-handed he would have to start writing from right to left instead of left to right.
