So it seems not many of the contestants have used the Invert feature before, and the ones who have some knowledge of not just making art then putting it over the top, (often coming out with horrid results) have made an icon that is more or less black and white to start with and just some text relating to the theme. munna.
Cherii gets my vote because the icon has used the invert filter, but only as an effect, not as a requirement. The original icon colours are still visible in the areas which matter (focal), although I reckon the invert could've been more subtle or further from the focal point.
I really was expecting some spectacular, crazy insane yet inspirational piece from munna being one of the only artists around here using the invert filter when not required to. Oh well, good work Cherii.
