Giraffe Zbrush Head Sculpt

So it has been a while since I last did a bit of zbrush sculpting. I have just watched a youtube video - the Flipped Normals guys on how to improve your sculpting faster - and I thought it would be a fun little evening assignment.
20 min sculpting an animal, I chose a giraffe. First sculpt from memory, and then a new sculpt this time with the use of reference images. Can you guess which is which? 😄

Illustrator Penrose Triangle

I am trying to get back to creating on my own time, and to that end I have started going through a lot of Illustrator tutorials on youtube, just trying to pick up a few tips and tricks and get some inspiration. And then add just a little twist to the final image so it is not just a total paint-by-numbers kind of thing.
Eventhough I think of myself as quite well versed in Illustrator there are still new tools and new ways to approach your work. 
This penrose is a nice little excercise and it can be found here; penrose tutorial
