Yes, We want the Xpose!!! LOL
Xcel,
Not only the biceps, the brachialis is really well developed. Lots of BO rows w/ palms down?...
The traps look very good, too. Deads, Squats or mainly lots of Shrugs?...
My friend, you look great. There are some things you can work on, but you know what those are. In a strange way, your strengths create your weaker body parts, e.g., your arms are very big, which make your shoulders look smaller than they are. Perhaps more than gaining tons of size (which we all want admittedly), you need to focus just as much on symmetry and balance, to create the illusion of size.
A note on your posing. I think you generally (at least from these poses leave yourself too open. Poses like your first and last ones, for instance, require massive size for effect. You can still create that X look having only 1 leg flaring out. For example, you might try the first pose with your left leg a tad more under your body, the right one out a bit more and the left hand tucked in tight behind the head, kind of like abs-behind-the-head pose. Also look at your hands - in many poses (see the last one), having the palms toward the body to make the profile of the fists small gives the best effect.
About the trunks - in addition to trying another color (a maroon might look good on you), look for a European-style cut with the sides coming up higher over your hope.
Hope this helps, Bro. Again congrats on the show. As I've said, you already won before it started!!!
