So... first of all! Fantastic photos of a very cutie and interesting spider!
The first picture is (from my point of view) the best because of the perspective, but it's a bit blurry. I would maybe try to sharpen a bit more.
The second one is pin-sharp with a perfect focus, but it's a pity to see this wonderful spider just from the side.
The third one is a very good mix of both. So sharp and a good perspective, but the background is.. let's say... oookkkkk.
But again. In general the photos are really great!
