I LOVE THIS STYLE ❤️❤️❤️❤️❤️
Okay sorry
Now, some of you might be like, "Oh, that's stupid, I'll just go into Picsart and use the "polygon" effect." Well, people who thought that, you disgust me. Photoshop is a wonderful place awaiting you with open arms, and if you don't take on that opportunity to, enhance you world, with photoshop, your life will be photoshop less. Just saying.
Well yeah I'm lazy as well if you wanna use that style then fine but this way is....better
Remember to flatten the image before coloring in the triangles

1) Go into Photoshop
2) Add the image you want
3) Make a new layer
4) Outline half of the object
5) Make that layer the first layer
6) Make triangles and shapes (small)
7) Filter--> Blur--> Average
8) Copy the half to the other side
