It looks good to me, but here is how u can make sure it is correctly seated in:
Try pushing the little PCIE clip thingy one last time and disconnect the GPU, but dont pull it out if it disconnects and the right side of gpu goes slightly up then you know it is good.
And one last time, gently push the entire side of the gpu that is in front of the PCIE lines so it goes in and seats properly again.
Just push it, don't be afraid.
now I looked at the image once more before posting this reply, you can see the right side is slightly higher than the rest, this is because you haven't pushed enough
