Hello!
I choose Clone Trooper!
some refs:

hi Mauricio, I’m not sure, but this might be considered a little generic for the topic “sci-fi icon”, I wouldn’t like to see you work hard on it (great start by the way) and not being accepted…you might wanna ask Roberto for approval in the FAQ sticky…just in case.
Well if the model is one of the Clone wars Clone leaders we are kosher.
Like Captain Rex,
or Cody
RobertoOrtiz - Ok, I’ll do Cody.
I could then make another character and use only the trooper to join the diorama?
And the diorama must be exactly one scene in the movie? or can I make a scene of imaginanção but with the right characters in the movie?
Sampei - Thanks for the warning.
igorcatto - Thanks my freind!
reedomatic01 - Thanks men!
USAlex - Thank a lot!
I really like your flow Maurício. Really impressed with the edge work in ZBrush. Very clean and smooth.
WyattHarris - Thanks men!!! The zbrush greatly speeds up the work, it really helps a lot.
BertieRooster - Thank you!
RobertoOrtiz - Thanks men! I hope not to disappoint. =P
guhhh - Thanks a lot!
Some more update

Looks like a great start
