I bought a book last year called  “Action Cartooning” by Ben Caldwell. This book is an incredible resource, showing how to convey action scenes with energy and vibrance.  I was really struggling to make the punch in the second last panel come to life until I got some posing ideas from the book.

I’m not a big swearer, so I tend to use strong language very infrequently.  However, I felt that something slightly stronger was needed in the second last panel to further ramp up the idea that not just the henchbot but Fergus too has undergone a transformation.
