Less can often be more in editing the photo after. I find the colours un-natural. The nice thing about over-editing is that as long as you have the original, you can have another go

As to take care of sharpness, you may want to think about your camera settings. With a large zoom lens, it is important to keep the shutter speed up to a certain higher minimum, as the length of the lens can highlight any unwanted movement during shooting.

The EXIF information on the photos should tell you what combination of shutter, ISO, and F stop were used (if you can't remember). As mentioned, telling us those numbers would help in giving suggestions.

Finally, practice helps. I look at my early shots and often cringe. Practice, learning the technical basics, and a willingness to try different things help!

6:27 am. Time to go shoot Air India arriving in YYZ
