really dont like his leg, hard to imagine an astrea type of close melee combat mecha move with those legs.

also dunno the paint job or the photo shoot quality, the whole red impression felt like dirty, would have been better on matt finish combi with the existing semi gloss inner frame.

but on the upper body and the weaponry look quite impressive.

still dont forget this is 1/144 kit, my hands would shake like hell wanna mod a kit like this... kudo to this china modder that successfully made it out.

i try cut pieces before, a kit this small is a no go for me... (then again tonight gonna try arm extension...)

hg would be harder as when you bash them together there is a feeling of not right on the overall view (mainly the kit is from other hgs)

thats is why bandai is working so hard to come out all the new hgs that can mix match across hgs, can wait and see which hg fits your knight design.

and start photoshop to see 1st.

try have a look in wing gundam proto zero lines (fenice, honoo) and cathedral gundam, might have some parts you can add in your knight theme gundam.
