Reason(s) For Rejection: - Undersharpened (Soft)

[Delta Lima 001]

Thanks for the quick responses, sir - much appreciated.
Bringing my latest inquiry to this thread now:

This image recently got rejected with "Soft" and "Blurry". Blurry typically falls in the "can't fix" category, but as much as I zoom in and check every corner of it, I can't say that I agree with it being blurry. Please let me know what am I missing.

Can it be fixed and reuploaded?

Thanks...

Hi

I am new to JP and looking for some guidance.

This image was rejected for Undersharpened (Soft), but I think the problem I'm having is with image size, and here's why...

I was able to get the image approved on a different site as a 2MB size file, with 2500 × 1667 dimensions
For JP, I brought down the dimensions to 1280 × 854, as required, which made the file size only 614KB (I think that's where the quality suffered most)

I'm stuck because I doubt that adding sharpness will fix it.

Please advise.

I got an image upload error, so I hope these reference links will help:
