Any tips for photoshop? [my work inside]?

It would help to see what material you start out with…..
In all-purpose, I like the faded, burned-out look the pictures have.
What I’d stay away from are the types of collages that immediately show that they’re assembled from a bunch of pics and place together with soft masks. The overlays that look like multiple exposures on one image look better.
Try overlaying images on top of each other with some of the layer settings, like hard light or multiply.
I’d also stay away from the type overlay that distinctly looks like it’s been placed over the image.
I’d do one of two things: Either make it a caption on the bottom or integrate it into the image to make it a right part of it.
Could be that the typo becomes the type on a t-shirt in the photo, a newspaper clipping thrown into the collage or a note scribbled onto a pad…. I’m sure you’ll have plenty of thoughts.
The all-purpose rule is: the fancier the image, the more straight-forward the typo should be. You don’t want one competing with the other.
But for a beginner – looking excellent!
