I would not ecpect that CB will equip the Tanko box with additional heads as they did it with the single Shikami in blisters. But we will see. Personally I like the wok heads
I really hate to give criticism when I don't have anywhere near the skill you do, but the white paint on the abdominal plates looks a bit thick and chunky. Probably just the extreme close-up.
Don't hold it back. You're right, I still have an ongoing combat with white. It tends to get a chalk-like consistency, no matter which brand I take. A friend recommended the Titanium White by Schmincke, a german brand. I think I have to give it a try. Although the FastPanda is alomost a proper result
when painting white I do it with airbrush and just work into the shadows and touch up final highlights. Its so much more tiresome to get the same effect with brush. Maybe you can give this a try?
I don't own an airbrush, and I think I won't in the near future. I tried out some airbrushes, and was never convinced, even for priming. With all the extensive cleaning that is required and the masking I'm almost always quicker with the brush. Right now the techniques I use with a brush more than suffice for almost anything, and for an adequate white I'll find one soon, I experiment a lot. The White Glaze by Vallejo is a really good addition, you can feather the transitions quite well. And using the Model Air White with a brush also helps a lot. Just for terrain I see – and already utilised – the advantages the airbrush has. I painted some buildings, which worked quite well.
I was about to report this whole thread.... Painting that superbly good must be ilegal in some way Terrific job, I'm eager to see more from you.
