During the Covid-19 lockdown, i did a number of livestreams where i did Photoshop tutorials. I think that process inspired me to dive back into Photoshop after a couple of years with pause from the creative process.
In a couple of these images, I've used photos of my own son, but other than that, it's all created from stock images, most of which i downloaded through envato.elements. 

Here you can see a couple of before/afters.

Also, you can find links to videos with Speed edit or actual Photoshop tutorials about most of these right here:
