Sudoku Puzzles
I have been trying my hand at writing sudoku puzzles. Please try my puzzles and give me feedback!

Rules:
- Normal sudoku rules still apply.
- For each cell with arrows, the number in that cell is equal to either the total number of odd digits or even digits along the rows, columns, and diagonals pointed to by the arrows.
The Puzzle:
Archipelago

Rules:
- Normal sudoku rules still apply.
- Color each square as either 'land' or 'water'
- Each contiguous orthogonally connected set of land cells forms an 'island'
- Similarly, each contiguous orthogonally connected set of water tiles forms a 'lake'
- The largest digit in each island is equal to the total number of cells in that island
- The smallest digit in each lake is equal to the total number of cells in that lake
- The leftmost cell of the uppermost row of each island or lake may contain a number corresponding to the sum of the digits in that island or lake. Note that not all lakes or islands necessarily have their sum displayed. The question mark indicates that that square is the top leftmost square of an island or lake, but no sum is given.
- A circled cell indicates that its digit is equal to the total number of land squares in its 2x4 region.
The Puzzle:
"Rainbow Rain"

This is basically version 2 of my first puzzle, "Rain and Broken Mirrors". The break-in logic is identical, but now the remainder of the solve is harder (though it's basically a hard normal sudoku). The ruleset is also much cleaner and the puzzle is more aesthetic.
Rules:
- Normal sudoku rules still apply.
- Digits within a particular color must be in descending order from the top of the puzzle to the bottom.
- Digits must not repeat on any of the 6 marked diagonals.
The Puzzle:
"Mistyped"

Rules:
- Normal sudoku rules still apply.
- Color exactly 9 squares, such that every region, row, and column contains exactly one colored square.
- The numbers next to a row or column indicate the sum of the digits along that row or column, starting from the cell closest to the number, up to but not including the colored square on that row or column.
- However, 4 of the numbers outside the puzzle are incorrect.
- Cells separated by a white dot have a difference of exactly 1.
- Adjacent cells along a green line have a difference of at least 5.
The Puzzle:
"Double Bubble"

Rules:
- Normal sudoku rules still apply.
- Two digit numbers within tictacs are read as standard base 10 numbers, and are equal to the sum of the digits on the corresponding arrow. The red tictac and corresponding arrow are only red for avoidance of ambiguity, their rules are the same as for the gray tictacs.
- Cells separated by a white dot have a difference of exactly 1.

My First Puzzle: "Rain & Broken Mirrors"
In this puzzle, I was trying out a couple of new rules that I have never seen any other puzzle writers use. I am curious whether people find them too complicated/hard to keep track of. There is one central logical component that I was really trying to incorporate into this puzzle, and I kind of failed in that it's solveable without figuring out making use of this logical component.
Rules:
- Normal sudoku rules still apply.
- Digits diagonally across from the purple X's from one another must be different. For example, the bottom left X means that in the following grid, no two numbers shaded the same color can be the same:
- Digits within a thermometer must be in increasing order from bulb to tip
- Digits within a particular color must be descending order from the top of the puzzle to the bottom
