Nice work, Blackbuck. Both designs are very striking, I'd be hard pressed to choose between them. I like the attention to detail with edge alignment and the logical, well-thought out arrangement.
Thanks! - Personally I prefer the Erinys as I think I need to change a few bits and pieces on the Ishtar that aren't so LO such as the canopy framing and vertical tails. (That said, I did do the Ishtar quite a while back).
I completely concur with Kilomuse
Jolly FANTASTIC work there BB. Well Done old bean
Cheers!
