It looks like you drew over the original, or copied it somehow, changing a few details like the flag position. Its "copies of copies" alright. 
All that detail and yet you missed the flag position. 
I started to be a little angry about that, but then I realised that it was something of a compliment. No, I didn't trace it or use a grid or a projection or anything like that at all. I used only my eyes and my hands. I've had people ask me if I traced it, but never accuse me like you somwhat rudely did there. I feel about as good at that accusation as I would about someone accusing me of cheating in the MA. So, Thank You!
The flag is in that position because I ran out of room on the paper. I initially got fascinated by all the textures and shades in the folds of the clothes and so set out to draw the guys on their own. As it progressed, and seemed to be taking shape well it just seemed wrong not to have the flag in the picture. Since on an 8.5x11 page is only so tall when it's turned long ways, I improvised. I didn't want to leave the flag out so that was my solution.
If you think about it, if I were tracing the pic, I'd have noticed that would be a problem right from the start and just used a bigger sheet of paper, and it never would have been an issue at all.
I do appreciate the compliment though, thanks.
