There is a EE sexing thread, you should try posting there. From what I've learned from that thread, some features of your bird indicate a roo and some indicate a pullet. The comb isn't a typical pea comb, as seen in most EE, so that's throwing me a little. The tail feathers look pointed at the end, instead of rounded, so that looks more like a roo. The red patches on the wings are typical in roos in EE too. I'm not an expert though. Try that EE sexing tips and tricks thread. Post there.
