Actually, that is the in-game size; it is a component from the title screen. However, the title text is not the Title Pic in the real title screen sequence, so that isn't an excuse for that.
I was under the impression that the screenshot thread, unlike the Mapping and Improvement thread, was more so created for simply displaying graphical elements including videos, title screens and the like. Critiques are certainly helpful wherever the occasion, but I didn't get the feeling that it was a necessity to the screenshot thread legacy.
On that note, however; just because it is small (at this stage of planning, it is probably going to be the entire portion of that scene to be displayed in the title page, among others in other areas of the screen) does not mean that there is nothing to possibly critique about the "graphical style" as said; as the graphical style is sitting there as is.
For example, perhaps the colour scheme is over/under saturated. One actual critique of this has been that Lyra's head leaning right is a bit awkward, as it feels like the head is dislocated rather than turning. Trying to fix that up now actually, but struggling.
^ I did take up the extra work of editing and reup'ing the screen with the title after the Miek's first message about it, by the way.
