I noticed that that top-left and bottom-right circles in the "Please Stand By" loading screen are not the same distance from the main central circle. The one in Fallout 3 is symmetrical which means that this wasn't a design decision.
It's a very small issue (more of an annoyance than anything), which is why it can and should be easily fixed.
The image of it can be found below.
