The placement and orientation of "ВДНХ" platform appears slightly off. The length of both escalators is a few meters off, hence the imprecision in platform placement. Tunnels to the south of the station start curving almost immediately with R = 1500 m, there is no sharp corner. Tunnels to the north of the station have less curves than after this edit.
There is a lot of good details to the station in this and adjacent changesets, but the orientation of the platform and the adjacent tunnels needs to be reverted closer to the original state.
