Your first mistake was playing with the tension screw. You NEVER play with that unless it's a very old, sagged saddle and you know what you're doing (this is right up there with all the stupid advice about 'breaking a Brooks in', you don't, you just ride it). There's a chance you've already voided your warranty depending on the damage you've done.

I don't see anything scary in the photos, but photos are notoriously misleading.

If you're concerned, contact the supplier and see what they say. However, I'd suggest that if you mount it and ride it, it'll sort itself out (and don't go bending things, just put it on the bike).
