More button designs

Lead multimedia designer Marsha Matta has submitted another round of designs for the primary app button, as we continue the FVM app redesign, in preparation for the public launch in June.

Dene Grigar sent back the suggestion of stylizing the fort even more, with less detail and more visual punch. ... Here are the rough images Marsha made in response:

Response to those?
