That is the full image, but it is from the light novel, however I do not remember what volume. What happens is that there are few illustrations of the novel where Hal's full body is shown, and I have not read the manga.
Anyway, if you want you can use the manga pic, although I like it more as it looks in the novel.
Just read it earlier and enjoyed it, and added some few bits on the profile since there's a nice nifty mountain slicing feat. Town Level and Mach 2 almost seems like a good add on to the verse so there it is!
