They look pretty good to me. The scope in perfect conditions will be very sharp at any range and also with the 1.4X TC. I class perfect conditions as winter time with temperature close to 0°c. I find anything above 5°c can start to soften details depending on the range, the type of terrain, humidity and lots of other factors. If you get any softness then it will likely be something outside of your control rather than the optics.

I have suffered the same problem, and you dont realise until someone with more experiences points out things that affect images.
For instance...Paul C pointed out things like heat haze in long distance shots. You may not even notice this till you get home and view the files.
Here's an example.. ( apologies they're not bird shots, but just making the point )
first shot of the church was taken at between 1 and 1.5 miles. Canon 40D, 600mm ED80 Skywatcher, 2x Barlow.
The Sun was hot that day, and it was early afternoon. Bad !
Another shot of a cottage, 1 mile distance, same camera gear but not so hot, and taken early morning. The difference is obvious

Incredible!!! The first picture seems intentionally blurred with a special filter !

If atmospheric conditions are poor, but not hopeless, you can get sharp photos simply by taking a lot of shots. Some of them will be lucky and will cut through the air at a moment of lesser turbulence. The hotter it is (in my experience, the closer to noon), the more shots you'll need to take...
Here's an example from yesterday: a Great Blue Heron at about 140 feet, taken at 755mm f/6, with an extremely steady tripod + bipod, and a shutter speed fast enough to freeze the non-existent action (the heron was staying still). Live View + 10x was used to get perfect focus (and I could clearly see the atmosphere wavering in the Live View).
One photo is very soft (but also sharp in places — characteristic of atmospheric blurring) and the other is fairly sharp. Both were taken RAW and processed identically, and cropped at 100%.
