WHOA!!!
thats really an awsome job, i really like the metalicity of the shapes
A few suggestions for the final version:
-Make "FIRST" smaller, black, and put the periods inbetween the letters so people know it's a separate and an acronym. otherwise people might think that "first" is referring to order. it should be smaller so peopel realize that it is a different part of the title, showing origin. like "Austin Powers Goldmember" where the "Austin Powers" is smaller than the "Goldmember" because "Goldmember" is the part of the title that is specific to that movie while "Austin Powers" is the origin. make it like:
F.I.R.S.T.
ULTIMATE
ROBOT
CHALLENGE
but keep "robot" in white, not black like i have
-put a bolder black border around all the lettering. this will make the word "robot" easier to read. you also migth want to consider seeing how a metallic "robot" would look, though i think white might be better
