HH Family Logos

Working on a family of logos for a parent company and subsidiaries. All are video production companies so I wanted to include a note the the NTSC vectorscope.
The primary company is called Heggarty Holdings. I wanted to play with the idea of a lowercase H with an uppercase H behind it (far right)
The secondary company is called H2. I wanted to make sure that the look is tied closely to the main logo.
CPN and ES are kind of different. Each deals with different aspects with CPN providing equipment and manpower for corporate presentations, and ES providing video walls for event signage.
Definitely open to feedback on these. Hope to post a vectored shot soon!
