[QuasiOdo]

That's me in the picture.
Years ago, I honed impersonating Odo at a DS9-themed murder mystery we did at a convention. Later I refined the make-up, which I do myself, uniform (not shown) and performance at various appearances. The photo was taken just before I presented James Darren with a margarita on stage at another con. It was classic. No, BEYOND classic.
And yes, Rene has seen me, and, now I'm very lucky and honored to count him as a good friend.
Cheers!

I used Photoshop for mine. I have lot of them. To start off with I thought I go with the Alien theme. Just until I can make a Star Trek one for here.

Might hafta look into seeing what I can do with some software. What's the best choice?

Mine is my company graphic...which turned into my online identity.

The one above looks professional enough, a sort of takeoff on the Starfleet delta or the more like old Chyrsler "Forward Look" logo.

I didn't know mine was going to get reduced in size. It was just an 80 x 80 clip of a screenshot from my LCARS system. Maybe I should make a smaller one to get full resolution.

Nice, fitting to your title.

Mine is, well, me. US Army Dress Blues.

I just used a shot of a model I did a while back. Mainly because it was the only already-made avatar I had handy

Mine is a crop of my business logo.
The above Avatar is pretty cool.

Mine is a simple screen capture from "Tapestry"
