Do you think this is much better?
My issue is the current mockup makes me a little bit confused. At first glance it makes me think that the avatar was from the user who currently replied. Doesn't really occur to me that it was from the topic starter.
I don't know if it's just me or not?
Another issue is, i think there's too much noise on the left side of the list, which contains the following: (topic title, reply, reply time, badge, avatar, reply count, new topic icon).
So i separate things a little bit. As you can see the list is more balance and easy to understand.
Plus, badges is more visible and not overshadowed by the avatar
EDIT:
Just to clarify, i moved the topic starter avatar from left side to right side.
