Yellow is Damn hard to do. I play Space Wolves and i hated just doing one shoulderpad on each model. The Manager at the local GW did an Imperial Fist army and spent days complaining about painting convincing yellow. Im very impressed with this.
I really like the insignia and the drum clip, reminds me of the mafia and tommy guns. Nice work, would go nice with some highlights. Eight for the paint job and 10 for the idea.
