People Per Hour profile design

Description

Hi All,
I'm looking to optimise my People Per Hour profile and make my work examples better.
At the moment, they are just on a grey background and look a little childish. I want to make them look professional like a real agency, and in line with my new, quirky contemporary feel - maybe we can put them on phone templates, look more modern etc
The job is essentially to help me put my social media management for examples onto some modern templates / digital mock ups etc - let's say just 5 to start with.
I hope someone can help - I have been wanting to do this for a while
I have attached some examples of what styles I like below so you can see what I mean by mock ups and how they are put together to showcase my work :)
James
