Awesome modelling (very awesome modelling), but from an art perspective its all over the place. Composition is very erratic, as you have 3 focal points. One, at the end of the (coping?) saw; Two, at the barb on the barb wire: Three, at the circular saw. Try utilizing the rule of thirds and zooming out a bit, maybe re-arranging some stuff. With a bit of ajustment, you could have a real masterpiece.
