AFAIK the only output of DNA transcription are proteins but how are things like skeletal structure encoded? I mean things that are not functional specialization like the shape of my nose or the size of my forehead or the length of my legs.

DNA doesn’t encode “how” as much as it encodes “when” cells should begin to specialize or begin to show certain traits. This timing depends both on the number of divisions that occur before a gene is expressed, and on hormonal signals that trigger groups of responsive cells to change expression in subsequent divisions.
