design for Noname Collage

Noname Collage

I am an app developer working on a interesting e-commerce project. I am looking for creative ideas. That's why I'm here.

Hi,

I am looking for creative ideas to construct an artistic collage from a given set of images.
The theme of the collage is shopping.
Some instructions:
There are total 30 images.
The collage should have 4:3 ratio.
All the attached images must appear in the collage, each image should appear only once.
Each image should appear without its original white background.
The images should be altered as less as possible (no color or saturation changes). You can add effects as borders, shadows.
The images can be scaled/rotated freely.
There should be no overlap between images.
You can add any other graphic elements (text, doodles, etc.).
The background of the collage should be white (you can add background elements, but white should be the base dominant color).

The final result should look artistic and creative.

attached zip with 30 images.

I've attached an example collage that I did.
You should't stick to any order or images that displayed in this collage, this is only for example
I am looking for graphic elements that could beautify the collage.
