Your stripey Pegaceratops reminds me of Roe's stripey Triceratops ( [link] ). In retrospect, "Dinosaur Days" wasn't a good book (even for 1985). However, it does bring back a lot of memories.
Um... are you asking if you can have the original drawing (to which the answer is no)? Or are you asking if you can draw your own (to which the answer is fine, just don't directly copy me and tell people where you got the idea by linking me in the description)? OR are you asking what reference I used (to which the answer is visiting Cliff an awful lot)?

Also are the wings made of quills?
