idk some parts seems so oversharpened maybe because of some brushes you used, while i see the stock less sharpened than some areas, plus the text seems...strange, like if it was low quality and you sharpened it badly...
i don't get this kind of "style" i mean, not the overall sig of course, but the colours, the sharpen and some bits seems totally randomish to me...it may just be my personal opinion tho
