It’s a windmill…
I used only Blender, and the background, which is cloud and sky, is a picture from Google.
I loved to have any kind of feedback, not a denunciation. Thank you 
That is very nice. A bush or two in the foreground would be a nice addition. I like the way the clouds mirror the little hillocks on the ground.
Looks really good, all i say is, it would be good practice to make sure your textures and reference photos are either owned by you, or are licensed under a creative commons 0.
Agreed, if you just pulled random images off of a Google search, then you likely have violated the copyright on several of them since they’re likely neither public domain or creative commons.
