Logic Puzzle #37 - ¼

 ¼

This is a new puzzle of mine. A quarter of this fillomino has already been given, and the path to determine the rest is quite nice (I think, at least)

Rules and link

Divide the grid into regions of orthogonally connected cells. Two regions of the same size may not share an edge. Clued cells must belong to a region containing the indicated number of cells.
