flow is good but i think text co uld use some improvement....or something iono it just looks a little off i think the smudging should be shown a little bit more but thats about it ^^
maybe the lines/c4d going to the left of the tag, or the blue soft brushed parts on the tag.. maybe ; and with the tag, i think the color brightness and lighting are too eaven across the whole canvas, if lighting and color brightness is improved around the stock, it'll draw more attention to it, making it a better focal point. and not only improving the focal point, it'll improve the whole sigs quality ^_^ good job though
oh woops sorry i was reffering to the soft brush hehe...i dont know i dont really like it for some reason but thats just me i think its a great sig
