I really like the stock model, and the concept. But it always seemed a little too busy for me. I also didn't quite see the Harbinger carrying a banner.
I saw someone do a similar conversion (he used a different acolyte to carry the banner) which I really liked, so I did one too.
Here she is:
Need to fix a small gap in her belly with some putty, and I also plan on doing something to make the pole less boring.
She is also missing her shoulder pads (which I can't glue yet cause they will prevent me from painting) which will be swapped for knights exemplar shoulder pads that both look better size for her, and will tie her nicely with my exemplars.
Hope you like.
