I painted these for the local enviro group we’re involved with. After several iterations and votes between members, we’ve settled on the sky REF with white-bellied sea eagle as the common-use logo, and the mangroves for larger, framing illustration uses, such as events, banners, shirts, etc.
Mangroves and eagle were painted in traditional watercolours, and then refined in PS.
Here’s a few of the iteration passes. The duck-bill almost won, but I’m sure we’ll still find a use for it elsewhere.
