I uploaded full-sized, untouched RAW format files
That's not a RAW format file, that's an un-cropped JPEG. RAW files for Sony would end in .arw, .srf, or .sr2, and be 10+MB in size.
That's ok, however, as I took a look at the JPEG (the RAW file would help mainly for exposure, color, etc...), and can tell you the photo is pretty soft. Whether that's because the focus is off, or because of your lens (some lenses are softer than others), I can't say.
The softness, coupled with the fact that there will be a fair amount of cropping needed (down to 2700pix or so) means that to bring this shot up to acceptable standards will involve a lot of work. I'm not saying it's impossible, but you'll need to spend a lot of time doing some selective sharpening, as there are some areas that need a little sharpening, and some that need a whole lot. You wouldn't be able to blanket sharpen the whole image, because if you applied the amount that was needed for some areas to all, then some would be quite visibly oversharpened.
So... the level of softness in your shot is something that can be overcome if the shot fills the frame, but because you're going to need to crop 40% of the image, it becomes a lot more difficult to hide.
If you want more advice about what may have caused the softness, or about how to proceed with an edit if that's what you want to do, let me know.
