And remember back in July that he finally posted his first content in that section with Amy Rose only?

Now here comes the strangest part in all of this. This model right here that he had uploaded on another site.


Was uploaded in Feburary.


And here is his current model that has been on the site since July.


Now, here's the big question. Why did he uploaded a modified version in February and uploaded a non-modified version in July?
