Long story short: Woke up actually refreshed and filled with energy. Took my chances and did all the remaining models in one go. Albeit a bit lazily done as I was running out of juice.
This covers all the Sonic Models (unless I missed one) and some extra models from SynjoDeonecros that fit the Sonic universe and were made by KabalMystic. Feedback and error reports are welcome, they might not be fixed immediately. For more info read the Patreon post
