On the new models, I think I may actually be disappointed.
I mean the Hydra/Kharyb-whatever-esoteric-consonant-combination-GW-pulled-out-their-collective-asses-this-time are a bit lacklustre in my opinion. The witch elves are 'okay,' although it may be just the paint that gives me that feeling. The dark riders I actually feel are a step back compared to the pewter ones, save for the horses.
That in itself is faint praise, for the old grinning demon elven steeds were a godawful travesty.
The Black Guard and Executioners were some of the best models in the range, much like the pewter Phoenix Guard were for the high elves... The Executioners were without doubt my favourite dark elf models.
And GW did to them what they did to my beloved Phoenix Guard. They look awful. And I don't think much of the new Black Guard either.
To comment on your picture Silver, that's not far off the comparison with the two 7th ed books either mate. Black Guard wiped the floor with anything the High Elves could throw at them in 7th too. And by the looks of it, that's only gotten worse.
