Just learning to play the guitar myself and at least personally, have found D to be a pain in the ass of a chord shape. I can switch between A, E, and G all day long, but throw a D in there and I have to slow down and be a little more intentional. Muscle memory will happen, but for the combination of my brain and that shape, it happens more slowly. I don't think I'm the only one, either, because it was called out specifically by the guy who did the video lessons I'm using.
Might give it a try later, though, thanks for the hint there.
The cool thing about the D shape is you can move it up the neck. Move it up 2 frets and its a an E, 1 more and its an F. And so on
The roots fall on a pentatonic scale which works well with basic rock music (see the referenced TNT song by AC/DC).
Maybe change your E and A to E7 and A7 if you feel like it. They're easier for beginner guitarists to play anyway.
