No you really don’t have to.
But this is what I did with all the dinosaur drawings. The senior final was to create a book, and I did and ABC dinosaur book. Because we had a limited time of really five weeks to put it all together the book is only A-L. I’ll finish it one day. Part of it was also to make it a publicly available book in case the professor wanted to buy it to use as an example.
Also if I offered to open up for commissions would anyone be intrested?
