The duel use of chainsaws in the thighs is my favorite part of this. They serve as greeble and at the same time connect the rest of the limb to the main body. I am honestly surprised that it even stands. Great stuff!
I like how balanced this mech looks. The way that you've posed it reminds me of a soccer goalkeeper or skier: flex and ready for action. The machine looks as though it would be heavy, with its armour but agile too.
Great to see a new post from you! Hard to go wrong with this colour scheme, and your building style is perfect here. The use of chainsaws is especially brilliant, impressive how you've managed to make them fulfil both a functional and decorative role equally well.
