Hey Blackcare,
You are selling yourself short there, your transmog is very very good! 
Have a look into the sets here and also into individual equipment here.
Some sets that may be to your liking (no purple though):
Heroic 10-man tier 10
Heroic tier 14
LFR tier 15
Additionally I used WoWhead’s tool to just craft a very quick Shadowmoon set that you might like! No fel green, but check it out!
