Aha! A landscape! And not a bad effort either. You asked for suggestions, so here goes. It's a little bit dark, looking about half a stop underexposed. That can be cured very easily in processing, just by moving the Brightness slider a touch (increasing the contrast slightly might also help). Also the foreground is a bit too cropped because it makes the trees and the monument look as if they are on different land masses, which - presumably - they are not. If it can be reframed, I would drop the bottom of the picture just a little. Other than that, though, no problems. The sky is excellent.
I wouldn't worry too much about a tripod. The days when cameras were made of brass and weighed a ton are long past. As a general rule of thumb, as long as you keep the shutter speed numerically greater than the focal length (which would be 1/250sec on a 200mm lens) you should not suffer from camera shake. If your lens is an 'IS' (Image Stabilization) type, you can safely drop that speed to about 1/60sec. I believe that yours is. If you are still in doubt, I suggest investing in a monopod. This is, essentially, a tripod with two of its legs missing. The idea is that between it and your own two legs, you effectively make a tripod. Actually a monopod is much more suited to an autofocus camera than a tripod is. You will know how you half-depress the shutter release, to establish focus, and then hurriedly recompose before tripping the shutter. That is easy with a monopod, just a quick adjustment of your body. With a tripod, it's a much more complex operation. You can pick up a perfectly good monopod for about thirty quid, although you may need to add a tripod head to that before you can bolt your camera to it. Worth checking out.
