You really are a productive little critter aren't you. This plog is just bubbling with activity. Those necros were painted really fast, looks alright though. The orbs look really spooky.
For the morghast blades I definitely think you should be keeping with the green theme. In other armies a clashing colour could have worked really well, but green is just so well tied to your army. With that in mind you could try doing mirrored blades on them. It's a bit tricky, but if you'd like I could link you to a tutorial about it. As inspiration this necron serves well. An other cool thing to do would be some sort of green marble effect, or lighting even. Freehanded crackling patterns criss-crossing across the surface.
