Here is my comment :
The following are a few basic criteria to make a good photo.
1. What is the main objects of the shot ?
There should not be more than one main objects in one photo
===> White flower ? It is too small to be main object ;^-(
2. Is the **most interesting part ** of the main object placed at any one of the four 1/3 point in the frame ?
Straightly follow this golden rule of third as a beginner.
===> The white flower is not at any of the position of the frame
3.Can the main object attract the viewers at first sight ?
Is there contrasting color (eg red on blue, black on white), shape, dark and bright, content (eg. action, gesture) to catch viewers' eyes.
===> Yes White on green make the flower stands out
4. Is there any distracting objects
The easiest way is remove distracting objects is to crop it much tighter.
===> The blurred white flower on the top right attracts my eyes.
eg. not useful objects like leave, unrelated person, bright reflection which can be excluded at the time of shooting.
Post process is the final part of photography. Learn Photoshop to crop (cut out not useful part of the photo), rotate, adjust contrast, sharpness, color saturation etc.
When you review your photos, ask yourself the above 4 points and you will improve immediately. Post the best of your photos here not more than 1 per day and ASK for improvement suggestion.
===> All in all the main object is too small.
Suggest to crop the white flower much, much tighter.
Happy shooting !
