In my opinion, full head. No hair loss at all. This first one was just a bad photo, with partial wet hair, pointing upwards, stuck together, under very bright light.
Take pictures every 1 to 3 months, and see how it looks. Take 2 from the top like this. Wet and dry. 1 from each side with hair pulled back and 1 from the front with hair pulled back. As long as it stays looking like this then you are fine. Try not to stress about it in between pictures, try not to reach up and touch it all the time or check it in the mirror. Take pictures and move on, then take them at their time. The pictures will show if anything changes, AS long as you take them as close as possible to the same angles and same lighting. So go ahead and choose that set up now and take some. Then again in 1 to 3 months. So let the pictures do what they are supposed to.
Edit: Also on the picture you just posted, in case you wanted a detailed opinion. See how the light is hitting the front and left top of your head more and we can see the hair stuck together more, and through the hair a bit. That is only because of the light source, and the hair being together. Then towards the right top and back we can't. There is no hard light source there and it is shadows casting not allowing us to see through at all. 100% if you change the light source it would look the same from any direction. Your hair seems to be descently dense and thick. You could pull off a slicked back hair style like this with that density and hairline.
So, just take pictures and if anuthing changes then you know something is up, as long it stays the same you are good. And my last advice is, if you continue to just worry and worry, then maybe try 0.25mg of finasteride a day just for peace of mind, and it should, if it works, keep your hair anyway. I typed way more than I meant to.
