I had fun adding a winter background to my whippet drawing which is now for sale as a card on Etsy. Juneallanportraits@etsy.com
Adding a falling snow effect in Photoshop creative cloud thanks to YouTube tutorials is fairly easy but I have to replay the instructions about 10 times before it sinks in!
Photoshop is so useful but I use it on a need to know basis - which means I don’t know that much until I need to. Maybe I should do a photoshop course but actually I think I prefer my hit and miss approach.
