Odds are that the quality of your images are more up to you than the camera. A "good" photographer can make great shots with relatively simple, inexpensive gear. That said...
Upgrading your lenses would most likely give you more bang for your buck, than changing your camera will. Especially the 18-270mm. It's probably slow focusing and that type lens usually compromises in other ways: close focus ability, image quality, ability to shoot in tricky lighting conditions, etc. Not sure about your 50mm lens... Canon has made and still makes several different ones, some of which are pretty darned good... others, not so much. If it's the old 50mm f/1.8 II, might pay to upgrade it, for example. The 10-18mm STM lens is pretty darned capable and good.
You might benefit from expanding your lens kit. Depending upon what you like to shoot: a faster wide angle (20mm f/2.8 or 28mm f/1.8) or a macro lens (compact 60mm or 100mm), or higher performance and longer telephoto (lots to choose among), or something else entirely.
You also might look to your editing, workflow and post-processing. Maybe you can make improvements there.
When it's all said and done, I think a camera upgrade might be the least helpful thing you could do. Sure, a nice new T6i or T6s or T7i or 77D ir 80D or 7D Mark II would give you some new capabilities, too... would make for a very nice, fun upgrade. But I'd prioritize that just about last, after expanding your own skills, practicing more, editing your images more carefully, learning more about post-processing, calibrating your computer monitor, and upgrading your lens kit. If you can do the camera in addition to those other things... great. But I think a lot of people just get a "G.A.S." attack and run out, buy a new camera and think that's going to magically "make their images better". It's rarely that simple. In fact, a new camera with a bunch of new features and added complexity that you have to learn to use well might do just the opposite... at least initially you might end up with worse results.
IF you get a camera, I'd recommend sticking with a Canon APS-C model (such as the ones I mentioned above), so you can continue to use some of your better lenses and possibly some other accessories you've already got (It's almost always a lot more expensive to change brands or formats, such as "upgrading" to full frame, which most people don't really get much benefit from anyway.)
