Actually, mine has probably more than ten parts.XXDDD and yeah, i was indeed planning to ask him to take a shot of all the figures together. It would be really nice. And you know he has a full list of people waiting to comission him, right? Are you already at the top of it?.
well if you like the shape of that big one, I think the one to the left of it could work, since it's smaller it'll look more in scale (I think the big gun is for a 6 inch figure, while most of the other guns here came with a 4 inch General Grievous figure) I can paint it in more of a gunmetal gray or silver color to make it look more vibrant, so don't be distracted by the plain blackness of it.
