Haven't forgotten about this, just have been pretty busy. I have to throw a gloss finish on the wood base then mess around with the actual snow/ice base. I am happy with the mock up so far. Base coat done on the walker, just waiting on an order of paint to come in to start painting everything.
Haven't done much modeling for a bit, once summer comes my interests/hobbies change. I find modeling is more of a fall/winter hobby for me. During the spring and summer months I have a "Honey to-do List" and my hobbies turn to woodworking/building stuff. Winters on its way so it's almost time to pick up the AT-AT again!
