3 Piece Framed Canvas Wall Art Pink Gold Abstract Painting Water Flow Shape Modern Home Decor Ready to Hang 24x48 inches

Are these available in size 28x60 inch (28"x20" each piece)?

Are they framed or is it just canvas?

Hi, I bought this painting , but the mounting bracket is attached to painting horizontally, so how should I install this to wall?

Can these be returned if they look cheap compared to the pictures?
