My At-Rt in Kashyyyk was so huge and almost monstrous so i've now built smaller more accurate one- i now it's not in perfect scale yet- but it's much smaller- and i made two of them for my upcoming clonebase-dio (possibly i use it also in utapau- ,christophsis-, Ryloth or Mygeeto-dios all coming later this year or the next one, well at least some day...)
I use scouttroopers instead of arf-troopers because there is no arf:s in lego yet- hopefully lego will do them.
These are cool. I like the design. The only thing I would say, is the middle toe on the feet is bigger and sticks out farther than the side toes. Maybe switch parts around and use a 1 x 3 slope piece for the middle toe. Also I think the legs may be a couple tabs short. Just some suggestions, but these are great!
