Ohhh... I really like the clock with the video play button in it... not crazy about the heart because the topics of the videos will be more than just heart health. Maybe make the clock more prominent and change the color of the play triangle to make it pop.
Rather than the gray of the "by the minute", I'd love to see something a little brighter/aspirational... maybe a more script-y font underneath.
Would be nice to see some color alternatives as well.
Great start!!! Very clever.
