Hello, I made some "fanarts" (if we can call that fanarts). I would like some opinion and advice to progress.

I made three pictures, I used Amnesia 3D models and textures in blender, made some composition in it, and used gimp for the text.
Theses image are rather big because I use them as wallpaper, so they are 1920/1080, sorry for that.

The first one, "brofist" :

The second one, "Untrusted" :

And the last, "light" :

I hope you will like, and I have a question, if it is good enough, where I can send they as fanart, because I'm new and I don't know

Thank you. Iisnotninja, it's not really difficult if we know how to do so it's why I had doubt about if they are fanart or not. Anybody can do it with some training.
Because I'm new, I don't know how to send them as fanart, what I must do for that, I saw there is a gallery, must I send they in there ?
