Welcome to the forum, and the world of photography.
My first suggestion is, if you are not used to getting critiqued (or bashed, sometimes

) grow a thick skin and don't take it personally even if you disagree. Most

fangs

people just want to help you realize how you can get better or what you can improve on, so don't take anyone's comments as a straight up insult when they give their opinion on your photos.
And we start!
Either flowers bombard you or you want to be a flower photographer? You don't (always) want to center your subject (this case, being flower(s) ) directly in the middle of the frame, you're still a beginner and I suggest you to read some basic photography books that cover the rule of thirds, elements, etc.
Experiment with angles and composition<- how you frame photos, decide what you want to include, you want to look for things that might be distracting in the photo. Look for shapes and lines, try to make your photos refreshing and new.

If you're going to take pictures of things that have a million photos on them already, try to photograph it in your own way.
Keep shooting and enjoy your new camera.:camera:
