Initial reactions:
- Change the font. Any ol’ sans serif will be a big improvement.
- The sketches that show the product in use are great. The very first one (on the chairlift) tells the whole story.
- Why can’t I just keep a speaker in my pocket? And what if I’m a skiier or I don’t have the right Burton gear? That’s the big issue with the concept, in my opinion. I would consider designing a speaker for hitting the slopes, not just one for people who ride Burton. That could be an interesting project when you start considering temperature, wearing gloves (as you’ve already done here), waterproofing, placement, etc. That’s a much bigger project, but just an idea for future efforts.
