Must get it out of my system and 'splain it. :thumbup:
I don't care for the ampersand. Two more characters gives you the word "and."
"Box set" is two words on front and hyphened as "box-set" on back. It does not need the hyphen at all.
Should be a hyphen before "level" when used as a descriptive adjective to a noun: expert-level players. They are not "level players"; they are "expert-level players." Same with "expert level breaking." It's not "level breaking"; it's "expert-level breaking."
Get rid of the hyphens at the end of the line. Looks awkward to have partial syllables at the end of a line. Bring the whole word to the next line.
Space missing in "10ball" on back cover.
Get rid of ampersand and use "kicking and breaking" instead on back cover.
Ampersands are Latin symbols usually used most often in titles of companies or organizations.
Title of DVD is fine, but when used as a noun, as on bottom of back cover, it should be a "13 break-and-runs."
Back cover has 3-disc box set and front cover has "3 disc box set." [Impressed that you know it is "disc" and not "disk."]
Colon usage with all-capped titles and then using it again after "Lesson 1" is redundant. I would get rid of the colon at the end of the all-capped titles.
I feel better now!
