Think this is Tau-y enough?

This is currently at the top of my list for a Riptide proxy.  Master Grade 1/100.  So it will stand 6 or 7 inches tall.  Hard to tell from the leaked photos, but I think that's close to the Riptide's size.  Cost about $45, so I'll be able to get two for the price of a single Riptide kit.  I have several kits I could use, but they all look obviously Gundam.  I think this could pass for some type of experimental Tau design.
