My First Polygonal Art

If I was to be honest its a great 1st attempt. Your background choice was great as well since you made that also a poly. Theres many different ways to make a low poly design with others taking longer, but being more detailed. I recommend you go to illustrator and make the shapes with the pen tool instead of blending colors. This is so it could snap together and keep the overlapping look from appearing. Great job on the dog.
