Pre-Production
I started by selecting a photo I wanted to use for the portrait. I had to do a family member so I decided to use one of my favorite photos of my dog. I pull the photo into photoshop to resize and posterize the photo. Once I did that I made a new Illustrator file with 2 art-boards, one for the photo and another with the photo to use the pen tool on a layer above it.
Production
I started but making outline of my whole dog and then outlines to split up the photo up into main sections. Once I had my outlines I used shape to create triangles of different sizes inside of the outlines using the pen tool. Doing this give the photo the low-poly look it was supposed to have.
Post-Production
For the most part I liked how it turned out. I wish there was a little more color or something else I could have changed with the eyes but that is all I would change.
