The garlic smell is a pretty good initial indicator: the main danger when foraging for Allium ursinum is lily of the valley, which doesn’t smell garlicky.
If you want to double-check, look at the cross-section of the stem.
It should be triangular to half-moon shaped (sorry for the somewhat blurry pictures):
The underside of the leaves will be matte while lily of the valley has roughly the same color and sheen on both sides. When you look at the general appearance, wild garlic has softer leaves which tend to bend over a bit once they get close to the final size.
Wild garlic grows out of little bulbs, but the connected part is in the soil. Above ground, it will appear as separate leaves (lily of the valley has a common stem above soil):
And a patch as grown as yours will already have formedflower buds, which you can see if you push the leaves aside:
Once the flowers open, an id is pretty straightforward - and you can probably smell them from a distance.
I enlarged and checked your photos and marked flower buds:
Just a quick remark re. confusing wild garlic and lily of the valleym The young wild garlic leaves appear a lot narrower and upright, which makes them much more similar to lily of the valley. Once they start to droop, the differences become more obvious. This picture was taken about two weeks ago and I’d estimate yours looked like that about three weeks ago:
