This is my first fillomino puzzle , and it's kind of hard to rate the difficulty but I landed on 4 stars. Please share in the comments if you think otherwise !

Fillomino rules apply: Divide the grid into regions of orthogonally connected cells and put in each cell the size of its region (1 to 9). Regions of the same size can't share an edge.
There are four hidden, non-overlapping 3x3 boxes in the grid, each containing the digits 1 to 9. If boxes would share rows or columns, digits within those boxes can't repeat in those rows or columns (ignore digits that aren't in a box).
Digits can't repeat within a cage. All cages have the same total.
The digit of a cell with an arrow is equal to the number of other regions that can be seen in the direction of the arrow. If a region can be seen more than once, it is counted only once.
All 1's in the grid must be inside a 3x3 box.
