I think the idea has some merit, but i think there is too much going on, which is the focus? I cannot understand why there is a giant jar of poison AND a chainsaw, because it is just too much going on at once... or they should be better linked visually if that is the symbolism you are going for. as it is, it just doesn't make any sense.
this is really cool, i love the clean look of it and the way the stumps look. but i also think there is a bit much going on, or at least for the way it is composed. if you put the chainsaw on one side of the woods and the poison on the other, it would balance the whole thing a bit better. i would say just try messing around with it a bit, because you have some really great elements to a good design here
