Kerning with HALO is too much. Reveille in the same typeface and near the same size kinda throws it off a little. Having the Spartan in the background is a nice touch, but the Armor and title are competing for space. UNSC emblem on the right unbalances the picture by becoming more content heavy on the right side instead of creating a balance. Your title also looks like it is low-res and grainy compared to the spartan and UNSC background.
Some initial typography clean-up will greatly benefit your title that is coming along nicely.
