I modeled this helicopter in blender
BTW this is my first model I ever made apart from terrain such as trees, land, mountains, rocks, etc
This is my first ever like real model apart from those things
KEEP IN MIND THAT I WILL BE ADDING THE LANDING FEET IN ROBLOX
But other then that any feedback would be helpful!
Pictures:
I love the low poly style so much, great work on this dude!
It looks pretty blocky, try smoothing it out.
Im pretty sure thats the style he was going for.
Yes I was going for a low poly style
I’m giving credit to you because it’s you’re first ever time making a vehicle, and in this case, a helicopter. Though I’d like to give some feedback since you asked for it 
.
The back roter is way too small. The main roter on top is way too low, look at pictures of real helicopters to help invision this. You got the form-factor down I’d say except for the sides, you put this big thing there and I’m not so sure what it is, I know your model needs some life but that isn’t it- it’s awkward there. I’d remove it.
It really helps looking at real-world pictures of these things, or even creations people already made.
Other than that, I see you will be a very talented 3D modeler, and I wish you best of luck. 
yeah, it just looks very blocky around the window though
Thank you for the feedback! I will be fixing these issues
Overall this is really good! The shape of the body could be slightly better but the tail looks perfect. One other thing I would recommend is making the propellers wider as they look a bit thin. Other than that this is a great first vehicle model!
