Heya, Gunpla,
Wish I could call what I did to my Krote, a "mod" --- it was literally a Hail Mary pass, and a very messy one at that... I literally pulled the split foot pieces back together as best I could, then applied CA and Zip Kicker. Planning on tackling the damage to the feet with weathering, dirt, etc.
Will add that one to my list of models to take pix of when the opportunity presents itself.
So my advice would be to seal and reinforce those ankle joints when you've got your pose figured out and if possible, reinforce the foot's "arch" with sheet styrene, epoxy putty, etc.
Arg! Now you're making me want to finish my Krote! Arrrrrgh!
Keep up the good work on your Krote, A --- love the turret and riser from the M113/132 flame track, dude!
Regards and Aloha,
Johnny B.
