No, not at all actually. The title screens arn't usually flamboyantly purple, and are done by professionals.
It also wouldn't be a good title screen, because it has to do with HL, which they already have theirs done. Maybe if you were making your own game, it would be ok, but other than that...I'm not to sure.
BTW: the one with the guy on the right fully solid, with the blue HL symbol is the best (not with the lightning in front of the guy)
