Thanks! Yeah, just Reaper + water for everything but the metallics. I think a bit of water gets added to the paint through the wet palette. Then I just add some more as I feel necessary. I'm not putting in a ton, but as I apply a layer I can see how it's covering. Is it too opaque or can I see some of the color beneath it? If it's too opaque add a bit more water until I'm happy. Well, that and working gradually from one shade to the next. The bigger the step the harder it is to blend.
There's something to be said for not letting smooth transitions govern all of your painting. There's areas where smooth transitions are appropriate and there are areas where it's not as critical. If you're going for dramatic contrast, then that effect can supersede the desire for smooth blends. I just posted some of the raw pictures I took of Redghar
here,
here, and
here where you can get a much closer look at how the color was applied. There are certainly areas on the skin and cloth where I'm striving for smooth transitions. But there are other areas, especially on the face and leather sections, where I worry less about the transitions and more about the overall effect I'm trying to create. Hopefully that is helpful.
On a related topic, I was playing around with my video camera last night and took some shots of the nearly finished Redghar and the knight. No sound or tutorial, just rotating the figures so you can get a look at them from various angles (and so I could test out the video from the camera). It's not exactly like seeing them in person, but maybe it's a bit closer than the normal images I post.
Looks like the size is limited here, but there's a bigger version hosted over on my painting blog:
