Long pins for Pinterest - tips

For a long time I've heard about the popularity of long pins for Pinterest so I decided to group in long pins some illustrations I've done over the last months. Here're the first 2 pins with the fairy tale illustrations I've been doing. In case you're interested, the measurement that you have to take into account when creating the pin is 328 PX wide and it can be as long as you want. I wrote the topic of the illustrations at the top together with my website so people can find my designs.
Let me know if you're on Pinterest because I'm looking for new boards to follow. Happy pinning!
