Blending pictures in a collage

[mtvs22]

I had 3 pictures originally imported into pdn into 3 separate layers. I cropped the pics, arranged them where I wanted, and then merged the layers into one, making a collage. I cropped the pics using the lasso tool, so it wouldnt be a bunch of squares put together. I was hoping to get a more natural collage.

However, you can tell that the pics just dont fit together very well. Im thinking there must be a way to "blend" the edges of the pics together (where they all touch each other) to make it look more natural.

Anyone have any advice on how to do this?

Thank you

Have you tried:

Transparent gradients?

Layer blend modes?
