The first one looks the best, the other two are too basic and boring compared to it
The reflection on the leaves doesn’t look great so maybe try changing the material to Plastic instead of SmoothPlastic
The smoothing is a bit too much, maybe you could try turning shade smooth off and use auto smooth instead (if you used blender)
A part from that they look pretty good!
I actually used the 4.1 version of Blender, so the auto-smooth feature is already dead in this version, and I used the smooth by angle modifier to shade the model. Also, thanks for the feedback.
These low poly pine trees look great! I like the way they look with the green on them! Nice job on this! How long did they take you to create?
All three look good but the first one is the best
