Hello @joshua_ong,
Nice picture. I well know the feeling of taking a picture and then finding that it was not correctly focused.
There are a few things you could do. I use two post-processors for editing images – GIMP and Avairy. Both are free. (gimp.org) & (Avairy.com) Do you have a program that you use to edit pictures? In both programs (GIMP and Avairy) there is a tool for sharpening a picture. By using this tool you can sharpen the cyclist. However I’m not sure of any easy way to blur the background in either of these programs.
I hope this helps! If you have any other questions please feel free to reply to this message. 🙂
