I do like the warm/purpley color you have used in the edit you did. Can you upload a completely un-edited jpeg and maybe we can diagnose what you are doing in editing? It seems to me that missed focus would be hard to have with this particular image. More likely some kind of motion blur or shake could be the culprit for a focus issue.
I think that probably the majority of your issues lie with something in your editing-overall. Blur could definitely be a factor, but I'd like to eliminate a funky step in editing first.
