BMW M4 is my most favorite car while playing the racing game, so now i make the 3D blender file of it. hope you like guys...
Hello again! I'm only commenting because I do like your work, but I'd like to offer some constructive criticism. I do like how the front headlights turned out. The tail lights I'm not so fond of. I think my main gripe with this one is the front bottom grill. That area should be jutting out from the car instead of being flat.
One thing that I think could help you right away is knowing how to make a hexagon mesh, also known as a "honeycomb pattern". This is the mesh you created for both the front bottom grill as well as in the back. Your mesh has hexagons going straight from left to right, where a typical car grill will have a staggered pattern instead. The fastest way to make this type of mesh is to enable the "extra objects" ad-on. So go to file, user preferences, type in "extra", and put a check mark next to "Add mesh: Extra objects". Now in object mode, go to "Add", "Mesh", "Extras", "Honeycomb". This will give you a relatively circular honeycomb pattern, while many cars have the pattern longer along the y axis. So go into edit mode and scale it along the y axis until it's longer than it is tall and you're done! You could also make this pattern by hand (which is my personal preference) by creating a plane, adding one edge loop, scaling it out, insetting with "i", and then using ctrl+shift+b on the outer vertices to create the beveled effect on the outside. You can then merge the unused vertices that the bevel creates on the inside. After that it's up to you to add array modifiers to get everything in order.
I hope that gives you some insight on how to improve. I'm interested in seeing what you make next. Good luck!
Thanks for that, and that was very helped for me.
