Well, I've been doing a lot of 40k stuff, yes. But instead of classic navy designs, I now try myself at more Mechanicus Style vessels, and instead of pure codex work, I've begun story scenes on a whole new scale, which is a change of pace for me.
Of course, then there are also Spacebattleship Yamato fighters, something I have never done before, and the Babylon 5 ISAF ships & scenes, which are unlike all the League ships from before.
Not to speak of the Perry Rhodan designs, which I used as a way to explore a whole new way of creating spherical spaceships.
If any of these things do get boring at some point, I also have three entirely different universes with very interesting designs I always wanted to add to my gallery here, with some artworks already done.
All of this is to say:
I am aware of what I am doing and how much of it I'm doing. And I'm also aware of long standing requests like yours for ancient human halo designs. And, as I've done all the times before, I can give you the same answer: I might very well get to it eventually.
But it won't happen any faster if the question is asked over and over again. I don't have a fixed schedule, but I do have plans of my own.
