Nah. Your stitching looks fine. The only way to see the slight, and I mean really tiny, misalignment in the hind stitches is to stare at them fixatingly as only we do here. I do take some issue with the awl technique, but perhaps not in the way you might think.
All this attention to forcing the threads apart is working a bit too well, in my opinion. In your pics, the awl gash on the front is huge, There's little to be done about it. That's just what the tools we use do. The end result is as you see it: gaps between each stitch. The long gash is at least a third to half the pitch distance, making the little bit of thread showing look chunky, to borrow a word.
I went along with everyone else, too, taking the ride on Nigel's words and advice. Long story short, my stitching looked like your photos: all gaps and stumpy looking threads. I hated it, gave up, and went back to stitching in an edge crease. That is not to say I didn't get anything from the exercise. It's just the opposite. The deep focus and re-think on fundamentals cleaned up my bad habits and, with help, I "discovered" Tiger thread.
As a suggestion only, just to see if it's moving you in the right direction, try stitching a row in a groove. Use 0.8mm Tiger, 7 or 8 stitches to the inch. Sew the row as Nigel teaches it, wrapping the front thread over to put the needle through the loop. The groove helps to fight the tendency to gap, even if the awl mark is a bit wide. What you should get is pleasingly proportioned stitches, each stitch touching the next, and the ribbon-like thread pinching nicely at the ends to make a pleasant eye shape. I would post a picture, but my gear and lighting aren't of the same class as yours. I think it's the eye shape more so than simply the induced slant that makes it say "hand sewn saddle stitch."
