Another update:
Did a bit of work, its hard to find time between work/ Friday night drinks and planning for a holiday in December. A lot of work has been done on the feet, upper legs, mid hips crutch and head. Also pieces collected for the lower leg...

The two box parts around the crutch area were extended...

Parts collected from HG Duel and MG Destiny for the feet, head and legs...

I really disliked the feet on the dagger and original kit plus nothing in my bits box would fit the bill. So after hours of cutting and grinding I've made a basic shape I like. A lot more work is required...
The head was also bulked up with extra V-fins, head cannon and round pieces on the sides...

Upper legs knee joints...
The next major area of work is on the back pack and lower legs...
