As for Random Theme, I'm torn. I have a Babylon Five avatar that's perfect, but I use Bab-5 an awful lot, so should I try something different?
or
With a risk of having my geek card revoked, what is picture no.2 from? The girl (?) looks like an elf, but beyond that, I'm lost.

.
Actually, they're both boys.

It's from an Australian webcomic called "Terinu" that I discovered (and grew quite fond of in a low-key way). Terinu is the "elf" with the horns and pointed ears.
I was wondering whether to try something different, such as this, or to go with my staple of Bab-5 (and a scene I literally burst into tears at when I first saw it

)
Damn hippies! You can't tell who's a man and who's a woman anymore!
I like your B5 avatars... But the drawing is really nice-looking, even though I have no idea what it's about. (Could you provide a bit of a context?)
Theme. I just love how he manages to pull off an expression that
almost looks friendly, good-humoured and kind, yet is so very, very creepy at the same time. It just doesn't work, which is of course the point (in context: this is one of his more overt sexual-harassment-of-Kira moments, so it was definitely intended to be off-putting).
That's definitely a very creepy expression. It's from
A Time to Stand, right? Notice that humorous and likable-Dukat moments were almost all in seasons 2-4, starting with
The Maquis, which was really the turnaround as his character was becoming more interesting and ambiguous than a one-dimensional (and back then, rather pedestrian) villain/antagonist that he'd been up to that point. Then in the middle of season 5,
By Inferno's Light marked another turnaround as he became a full-fledged villain, but on a grand, epic scale, which he was throughout the Dominion occupation arc. Humor was gone, while all the creepiness of his character came through, but there was still complex and ultimately tragic villain (
Sacrifice of Angels). After that it was hit and miss, though I really liked
Waltz (apart from the 'true evil' line which was really on the nose) and
Wrongs Darker.... I never understood the argument that they had to make Dukat a "Satan-worshipper" to show people that he was evil

which is stupid and makes no sense, and besides, I think that between
Cardassians, Occupation of Bajor episodes (all 3),
By Inferno's Light,
Ties of Blood and Water, and the Dominion occupation arc, they had already shown that to the full extent.
Anyway:
