I have collected my drawings for you. I left them unedited (except for adjusting the whiteness of the paper and the blackness of the ink a bit), so you can see all the messy details, my eraser marks where I messed up the underdrawing and everything else.

I hope you find this encouraging to share your own work, but feel free to edit the illustrations if it makes you more comfortable!
