My Nurgle Heldrake is probably my favorite
Though he still needs a rider
I also love making orks, Heres a silly Cybork/ Powerklaw Warboss (He has a necron-ish body, made from a heroclix model)
With all my models, i use square bases for decorative additions to models (like
CSM combat familiars, i just move them when they get in the way)
