very nice chair
i'm working on stocking up myself - like you said, to have my own unique objects and one of the things I try to do is make the element so shadows work no matter what angle its placed in. Things like chairs make that a bit more difficult of course, since a true shadow should feature the legs. Actually doing cool shadows define elements that otherwise might be anything. For instance in my back-yard battlemap I used (in my opinion) very nice shadows to show a fence, so even though you saw the fence from straight above the shadows shoved you how the fence was built
looking forward to seing more
