Honestly I may be in the minority here but I think your hairline looks freaking amazing based on those pics. The slight imperfections are what makes it looks natural. That said, as the owner of the hair I get where you're coming from. But if I passed you on the street, or even was sitting across from you in a brightly lit cafe, I would have no idea you'd had a HT. All I'd be thinking is "damn that guy has an amazing head of hair".
If it still bothers you rest assured it'll likely thicken out more in the coming months, or you could try a bit of minox/derma rolling.
