I had some time this morning to work on the swan crest, and I am pretty happy with the results. I was torn between doing the swan blue, or copper, I needed something to break up the colors a bit and give the model some variety. Thanks to Ghoul for brainstorming with me on my options. The way I achieved the results is very simple.
First I started with VGC Brassy Brass. THen I started mixing p3 Battlefield Brown with the brass a little at a time. Each mixing I would "streak" the swan vertically with the new color. I did this until I achieved a nice blotchy looking copper color. At this point I started doing the same "streaking" VMC color's Bright Green, Turquoise Blue, and Sky Grey. After these coats dried I started hitting the edged with a 50/50 mix of Brassy Brass and Battlefield Brown. Finally I took some very thin Battlefield and add some random dark streaks in. I am really digging the effect and I think it does a lot to add a little color into the scheme with out being over powered.
