No problem at all, bro. I can see that you're trying really hard, and you're starting to get good at it.
The main problem you have to overcome is good light.
Start with rendering in "open" scenes (not indoors!), using good HDRI textures for environmental lighting and you'll immediately get a completely different result.
The main recipe for success in good rendering is to give the scene enough light. If you're afraid to "burn out" the scene with light, then deal with this technique, Canvases:
