This time I did an AK47 :D some improvements have been made since last model :D share and dowload if you like
Thanks for objective opinion :D I will correct and re-upload my model in my free time :D
Its a good looking model just needs some good naming so people can find each mesh easily and try to avoid using Ngons. Ngons mess up the subdivisions, loop cuts and shading and that's the issue your having with the circular pieces on the model. When filling in a circle , inset it a few times and edge collapse the center ring, then remove some edges to make it all quads. Try to stick with quads and then after applying modifiers start to remove unnecessary loop cuts from the model and it will be perfect. If you know most of this already please forgive me.
https://www.youtube.com/watch?v=tf3QZL8ahGo if you watch this eye ball tutorial you will learn about making a circular mesh using quads and edge collapsing then you can apply it to all your round pieces. Its the video I learned the technique from. I hope this helps.
An AK-47 (or other real-world weapon) is a utilitarian object outside of the scope of copyright. Denoting it as "fan art" is improper.
It is not a reproduction of a fantasy piece or an interpretation of an already-existing creative work.
I believe that if there's a single company that makes specific model of weapons then copyright law applies to it. But in case of ak-47 you're right, there's no one specific company that makes ak-47, muslims make their ak-47 from scratch at market squares and tent factories:)
I believe that in case of this blend that i've made https://www.blendswap.com/blends/view/86409 FanArt mark should be present. It's a real-world weapon, but it's also a specific model designed, manufactured and vended by an existing company.
"I believe that if there's a single company that makes specific model of weapons then copyright law applies to it."
This is generally incorrect. Copyright does not protect useful items. When an item is mostly utilitarian courts rule that copyright does not apply. Patent is what must be used to protect utilitarian items.
Copyright can protect sculptures and other works of authorship. Copyright generally does not protect utilitarian objects even if they have some artistic design elements, however.
Some companies recently have tried trademarking the silhouette of their gun, but then, again, their intent is of an improper nature when they try to use trademark law to enforce psudo-copyrights.
Not bad but some advice. Apply your modifiers, Name your meshes and clean up the mesh. Some of the shading is off on some parts, plus there might be some trademarking issues with your design and naming with out giving credit to the designer. Just my opinion, good luck and I hope you don't get offended. Happy blending.
