This one's nothing new in terms of recipe - NECA David 8 head + Toybiz ML X2 Wolverine body (see the wonderful work by ringomendoza), but it's my first commission custom, so it means a lot to me :)

David's hair had been cut off; helmet sculpted on then painted with Vallejo and Mr.Metal Color metalics; some bloody scratches sculpted and painted above the eyebrow. The head was attached to the neck joint with sculpey to be raised a bit for a more proportionate look.
Resculpted the chest; used some wires for the zip lining; black base-coat, lots of yellow layers, dark and even darker blue drybrushing, some shading.

Then I designed some box-art for Red Erik (with all appropriate legal garb =D). I don't have tools to make my own proper clam-shell, so I used one from another figure.
A translucent NECA stand included.
