Hello, enjoy this puzzle!
All feedback and comments will be much appreciated!

This is a bit more challenging than some of my previous puzzles, but perfectly solvable with some interesting logic.

Rules:

• Normal sudoku rules apply.
  
• Along thermometers, digits must increase from the bulb end.
  
• Digits along a purple (renban) line are a set of consecutive, non-repeating digits in any order. All crosses act as 5-cell renbans.
  
• Digits separated by a white dot must be consecutive. Digits separated by a black dot must be in a 1:2 ratio. Not all dots are given.
  
• The grey circle contains an odd digit.
  
• Cells in the same position within two 3x3 boxes cannot contain the same digit (disjoint sets) (i.e. r1c1 cannot be the same digit as r7c4 since they are both in the top left corner of a box).
