There looks to be a lot of dark blue at the end of those Class 720s, which makes them look quite “heavy”, compared to the Class 701 and Class 387 we’ve seen before, where the diagonal stripes overlap with the cab door, whereas the stripes start behind the cab door on these Class 720s. It makes me think that the Class 720s would look better in the lighter Network SouthEast livery. On the Class 701 and 387, the double arrow logo and GBR are on the red bit, rather than on the dark blue bit in front of the red bit.
