Can I achieve a look like this without Maya? Link is inside!

I’ve tried using freestyle. When I asked the artist (Eran Hilleli) he said he uses flat shading and hard shadows, but he uses Maya. I just really love the flat look he has going in his artwork, and would love to incorporate some of it into my art. If anyone knows of any way I can achieve this low-poly/flat look, I would appreciate your wise words!
