This was from the Fundamentals of Digital Sculpting course here. I've sculpted a lot in real life and a little bit in Blender, but never really learned how to properly understand the brushes. So this was a great course and I can't wait to start sculpting more things to show you all.
What a fantastic result, Harold is cute and I love that hat!
Very nicely done! I particularly like your "watery lines" over the shark, the division of the gray and white at the bottom of the shark, and your pearly whites for the eyes and teeth.
The top hat is another nice touch making it a little more uniquely yours!
The god rays look good, as does the background.
I'd say you crushed the exercise!
