So it seems like you just applied a rust texture to the M4, not really a big investment.
If you compare is to "Nova | Antique" and "Bizon | Antique", it lacks golden parts, wooden parts, and golden arabesques on the metallic part. If you wanted it to be different from the both I quoted, then you need to change the name a bit more I think. Maybe "War relic". But anyway I reallly think that the skin needs to be improved, it needs more details. For example you could add an area with the count of enemies it killed during war, in the form on group of five lines like |||| and one crossing diagonaly. You could also add a pinup design somewhere, like the americans had on their planes during WW2. Examples: https://www.google.se/search?q=ww2+pinup+plane&biw=1536&bih=755&source=lnms&tbm=isch&sa=X&ei=gMLhVLLJJ6LcywOcrIHwDw&ved=0CAYQ_AUoAQ
Basically add something that makes your skin more sexy.

As Ghost said it is a little faded but still looks nice. More pictures please.
