getting rejection for technical issue

Hi @shrikant24636917ls84,

Zoom your images to between 100 and 200%. A section of the first file looks like this 

It's looking dull, possibly a little underexposed or cool. Section of the subject is blurry - out of focus. There are grains on the subject - noisy.

This is also clearly underexposed (looking dull) and not sharp. The composition is a little out. You should include the tip of the leaf at the top. 

The line at the side of the the subject draws the eyes to its crookedness. While either of these elements for this subject are no reasons for rejection, it is good to pay attention to these details. What I do when I have crooked lines in my framing, is to remove the line in post processing, or while taking the photo to to make sure it's vertical or horizontal or use to create a regular shape. In this case it's better removed.

The second and the third images are similar. That will generate a similar rejection.

It would appear you're either too close to your subjects or do not have enough depth of field to produce complete sharp images.
