I really like the Upper half of the Mech, very solid and Harmonious. However I think the legs could use a little re-working. Try implementing the design of arms onto the legs. You'd be surprised how often it works for the better; Arms and legs are like brothers, similar but different.)
lol another Shrike... I had a character I developed back in my high skewl days named Shrike... I've seen a few others use it for their various creations, too... the entire time I thought I was being creative, and it turns out a Shrike is a type of bird, so it actually fits really well in this case
Anyways, excellent design, I like the setup! Stick some fat thrusters and a rifle/shotty combo on this badboy and you're ready for war!
