id say a little more detail to the sword aka some shading and maybe some more detail to the banner poles like a marble type pattern running on it and that would take care of any open spaces that stick out a bit much. also instead of black wash shading n the banner pole id maybe use a brown as it compliments the color of the pole better. lastly shrink the pic by at least a 3rd as its size is hurting the pic because its way to big. a very solid mini specially for being a non character etc with uber details and you have done a great job. just a little more oomph and i think it would propel it.
Very clean and neat! You should be proud...I'd say from this that you could do 8+ stuff if you went a few steps further on the highlights. And highlight/shade the metals too!
