dear master builders, need some experienced advice on the following.
this is a HG 1/144 Tieren Taozi Space Type from the anime Gundam 00
I've almost completed this build but got stuck with the legs...
this fuel tank comes in grey colour and in 2 pieces, it "wraps" itself around the lower leg which is in a different colour
i've chosen purple colour for this kit, now that the leg has been painted, it's difficult to work with the fuel tank's seams and then painting in grey
the 2 red circles shows where the fuel tank needs to be painted as purple as well
this is the thigh with the ankle joint already painted in gun metal, the shape of the joint is in weird shape very difficult to mask.
how would experts/sifus do these 2 parts? the entire kit is already painted and sitting in a box waiting for its legs for a month.
i stare at it everyday feeling lost

in fact i started another kit MG 1/100 Deathscythe and it's almost done as well.
help...
