Hiya rizzie and welcome to ThePhotoForum!
Congratulations on starting out your new hobby with such a nice camera.
Thanks for sharing your first results with us.
As suggested by JimmyO, next time you post, make sure to push the space bar at least twice between one link and the next, else all your photos run one into the other. And as soon as you know it's going to be more than three photos in one thread, give them numbers. I edited your post accordingly this time.
I like the first photo.
The others still show technical flaws or compositional flaws, but all in all you seem to be on a good path. You might want to try out one or the other software that helps you to further work on your photos once they've been taken. Such software can help you correct crooked horizons (as are showing in the last two photos here), it'd also help you "re-compose" a photo that hadn't come out its best in the straight-out-of-camera (SOOC)-frame by cropping them in a different manner, you can take influence on the colours, contrasts, sharpness of a photo and so on.
Keep posting, read a lot, and keep shooting!
