The corners of buildings are typically exactly 90 degrees. Unfortunately, it is pretty hard to achieve such result manually. There exists an option in iD editor to square a single corner (point) or complete building (area) by right-clicking an object and selecting according entry. Unfortunately, some manual correction and repeated squaring operation are often required.

There is no need to tag simple polygon of a single building as multipoligon with several connected lines

Hello and welcome to OpenStreetMap! It looks like together with intended edits you've removed some valuable tags, especially building=yes tag. That's why the institute isn't shown as building anymore.
Other questions could be: does this building have no defibrillator access anymore? Cannot this building be called ZM 1 anymore?
Moreover, the address of the SICP node needs to be updated if it has moved into other building.

Was Cita santehnika really closed down?

Do these new footpaths near the main road also wobble from side to side in the reality or go more or less straight?
In general - a lot of unnecessary points used, 2 points are enough to show a straight part of the road. Of course more can be used to show smoothness of a turn or to trace a narrow bendy footway in a forest. Please consider straightening paths and connecting ways.

The new way created in this changeset is tagged as an underground tunnel under this 5-story building - is it really so in the reality? As I understand tunnel=building_passage is more preferred for a way through buildings, where only the part under the building is tagged so, not the whole way.
If it was meant to be a way through the shop - I'm unsure whether this way belongs here, maybe tagging both entrances is a better idea

Also, I don't think that intermittent tag change of Sunu lake is correct. I was there last year and it is pretty full of water

If you'll look at your changes using other imagery at https://osmcha.org/changesets/84425776, you'll see that what you've done with bing maps doesn't correspond in other imagery

Hi, it looks like you've used Bing maps with a default offset (0,0). This is not fully correct approach. There are multiple imageries available, and if you switch between them, you'll see that the positions of the same objects are not really the same. So it is important to adjust offsets of used imageries before mapping, it can be done at the bottom of background settings' menu. I usually adjust offset to the major roads, so the lines are approximately in the middle of the road. Additionally publicly available GPS traces can be shown to be overlayed over imagery, your own GPS track can be used too.
Also it looks like you've mapped buildings along their roofs. This is cruicial for imagery like Bing maps, because you can see that imagery was taken from some angle. But the roof doesn't define position of the house on the ground, it's basement does! In this case I like to use Maxar imagery for our region, as the photos were taken approx. at the straight angle and you can't see the walls. So a point on a roof will be the same on the ground level.
I hope, this way we can build better and correct map of Daugavpils!
