The Storm Talon looks like a it was built out of legos. GW spents 100,000 dollars to create 1 molding cast, this is the possibly the worst looking miniature I've seen in years. Much worst that the dull faced turtle Skorne battle engine and Kingdom Death Wet Nurse.
The Ork Flyer is moderate at best. Paint jobs are nicely done.
The Necron flyer is the best conceived model. Thankfully enough, the designs is keeps pushing away from the Forge World tomb stalker.
