A more pronounceable name would be nice.

The images might blend into the page better with a vignette or larger curved edges.

In the replies, I feel like the name and post age's y should be centered with the profile picture.

The heart icon on the second post sticks out compared to the post age and reply count. It could be made smaller or swapped out for an emoji or unicode symbol.

I like the color scheme, it looks pleasant to scroll through, although this is interrupted by the bright colors of the images. There's probably some way to mediate that by playing with size or color filtering.

Overall a bit amateurish but not bad, I like it
