@pixelfed On the first look, I think the buttons below the picture should be in a different order.
The button in the middle feels the most accessible, followed by the right one (for me, right-hand dominant).
Bookmarking should be on the left because its the one used the least. Maybe the like button to the middle and the repost to the right.
This way liking becomes easier and faster, while the repost button keeps being convenient to reach.
