Thanks for some quick feedback. I've already tweaked the pic a bit, added more detailing to the bot and gun.
Doing a clone or something would be a challenge, but I'll get to it. Right now, I'm trying to beef up my portfolio with a variety of pics. I did this in Illustrator, which is pretty standard for graphics these days. My big gripe with this pic is the background being flat, particularly the floor. I need to keep working on it though, I've only been using the software for a few months now. But it's getting somewhat easier.
I suspect Illustrator is the soft the Lego comics are done in, if they aren't just 3-D renders. I'm sure Lego torso and heads are done with this program.
More eventually

I am a Satanist and not ashamed.

“I believe that if, at the end, according to our abilities, we have done something to make others a little happier, and something to make ourselves a little happier, that is about the best we can do. To make others less happy is a crime. To make ourselves unhapy is where all crime starts. We must try to contribute joy to the world. That is true no matter what our problems, our health, our circumstances. We must try. I didn’t always know this and am happy I lived long enough to find it out.” —Roger Ebert
