For depth-first (A is the root of the vertices in alphabetical order)... A would connect to B, then C, then E, then F, then D, then H, then G, then I, then J, then K. Go back to J, connect J to L.
For depth-first; it looks like you went from F to J. F should of went to D.
For breadth-first; blue part looks right. Orange parts should be BE, CG, DF (one you missed), DH. This changes the remaining the connections.
