"1st of all thank you LEGO for bag numbering. My grandson , who is 11, has built many LEGO's and some above his age group. He did find some difficulty by placing some parts of similar appearance in the wrong place. He and I both took notice how Yoda was constructed and now has started to build his own character using grandpas vast collection of extra pieces. Over all I believe this set is outstanding and looks just like Yoda.I do think the build is a bit difficult for the average 10 year old LEGO builder."
