Good table top quality on this Rhino.
One thing that I really like and sets it apart from all the other Black Legion Rhino's I've seen is the freehand Chaos star. Good job on that! I really like the rich warm yellow tone.
You should pay more attention to moldlines though, like on the spiky rack in the back. And it looks like you haven't painted the icon on the rear hatch as well as the Tzeentch Icon on the left side.
