Hi Tog,
No question you would do better with better equipment (like Canon L lenses), but in fairness to what you have, you need to learn to use the tools you've got.
I only looked at your first two images, but there are clearly focus problems. Only use the focus dot in the center of the lens. You are focussed on other items in the pics, and you must not be doing that. Use a tripod whenever possible, that will greatly enhance your ability to control conditions.
