Yes, there seems to be a pretty severe color cast. See below for my partial attempt it from the right side.
As for level, I suggest using any horizontal/vertical lines in the background. In this case, they would suggest you need a little CW
rotation (especially the verticals). You can always just leave it as is and see what the screeners think (but fix the color).
Both.. especially the right wing. Jaggies visible along the nose too.
Pretty strong color cast again, and the quality's not really there either (looks like due to heat haze/ jpeg compression)
Soft/Blurry, color, quality is lacking in this one too.
Best of the lot quality-wise, just needs a little brightening, and seems to suffer from compression too, but that could just be how you're saving it/uploading it. Motive probably is ok, but can't say for sure.
Also better with the quality, but the lighting conditions make for hard work in the editing. If it were me, I'd go with the first one. There are a few things that need fixing up (color, CA
, etc..), and it looks like it's suffering from some compression again, but it's probably fixable.
It seems that the case with your earlier shots is that they were taken with a camera that unfortunately wasn't up to the task. I see that you switched to a K10D recently, and that the quality of your shots correspondingly went up. Nearly all of my shots on a.net were taken with a K10D, so the camera is certainly capable enough. If you need help editing, let me know, as I've obviously had plenty of experience working with your camera. If you have the original files (raw/.pef/.dng preferable) I'd be happy to take a look and help you through the process.
