Noob looking for feedback

G3Renderworks

I don't have any 3d or photography experience so I'm looking to get some early feedback to avoid growing bad habits. I made a collage of my first three renders before and after attempted postwork in gimp. Again, I don't really know anything about this stuff and I've just been watching random tutorials to pick up tips. Open to any and all feedback/suggestions. Also interested in a course that has a more ordered approach to learning all the different aspects if anyone is aware of one.

Best tip is to find a photography club and learn with likeminded people, or a dedicated course if a club is not possible. Why? You learn to work with constraints and specific topics that help you get a rounded view and skill. A lot of it can be 1:1 transferred to Iray.
