I know, but the way and pieces you used to connect he hand connector to the Tohunga feet is exactly the same. I’ve seen some other MOCS using modified Tohunga feet like this one (Toa Macku (with custom Tohunga feet)) that explicitly said were inspired by mine an still look completely unique.
About the height, it wasn’t a rule in Artakha nor Helryx’s contest despite having known heights, of course, having a canon height helped the winner MOCs in the polls. However, there’s a more recent post by Greg where he said Lariska’s height relative to a Toa is unknown (Chat with Greg Farshtey | Page 863). He probably forgot he said she was Toa sized at some point, but in the end it means Lariska can be as tall as we want her to be.
