Hi there mate, I don't mean to sound negative, but just in case you weren't aware, scratchbuilt means its been made from cardboard, wood, foam, plasticard, greenstuff, using hardly any GW parts
these look too close to the real things that i really doubt they are scratchbuilt, i mean the rivets are exactly in the same place on your titan as the forgeworld one.
If they indeed are "Scratchbuilds" please please let us know how you get such professional results from raw materials, we would all love to know
