The main action in a log is usually without parentheses or italics, as the action summary is supposed to be that. Down below, I provide examples of what they look like, and for what they should actually look like. Simple + minor changes I believe, but consistency is always important. :)

Avatar upload log / Special:Log/avatar

Example:

23:39, March 13, 2016 Jack Phoenix (talk | contribs | block) (uploaded new avatar)

should instead show as:

23:39, March 13, 2016 Jack Phoenix (talk | contribs | block) uploaded a new avatar ([[File:whateverfile.png]])

Above, we actually show that the uploading the avatar is the action, where the avatar file is the provided summary, similar to how deletions are actions and reasons are provided in the summary in Special:Log/delete.

User profile edit log / Special:Log/profile

Example:

13:47, December 4, 2014 Some (talk | contribs | block) (changed section 'personal')

Should instead show as (or something similar to):

13:47, December 4, 2014 Some (talk | contribs | block) changed a section ('personal')

Edit: Actually, perhaps Special:Log/profile could support gender pronouns, where it would say "changed a section on her profile" / changed a section on his profile". If they modified Special:Preferences where they prefer not to say it, it would say "Changed a section on their profile". (Yes, it's a perfectly valid pronoun to use for singular gender-neutral context! Check it out, for anyone who doesn't know.)
