This looks awesome. Yellow is a brave colour to go for - and you've really nailed it. Purple and yellow work very, very well together. I especially enjoy the light-to-dark shading you've done on your purples - those scourge wings, the shardnet, just perfect.
I find the skin tones interesting - the first model with the glaive has a pale, purpley vibe whereas a lot of the others have more of a mild, fleshy look. It's rare to see mixed skin tones in an army - and it's good to see it when it does show up. Nicely done!
