I really like your versatility with changing between different styles. Great work! I mistakenly came across this site from a search for jumping monkeys (for a book I'm illustrating) of all things and this sketchbook link came up and found little about monkeys but found these awesome sketches. As you can see this is my first post, I just thought I should tell you how great I think your work is! Totally Awesome
P.S. I currently have 2 family members with Alzheimer's, both well along in years, but I have to agree watching them now compared to what they used to is quite challenging. You have my understanding and sympathy.
