Hello!

I advise using Maxar or ESRI imagery for purely aerial mapping, they have better resolution and (at least around Almaty) are more recent.

Also, I would like to ask to not snap/connect big areas (landuse, fields) to the road points - it makes it hard to untangle them and edit later.
If it's done only for convenience, you can connect right-click→disconnect to free all points of the new object after you draw it.

Cheers and thank you for mapping this area.
