That warthog is from halo 3, right? Also if you made the warthog from a pic on the internet you need to give credit. I say this because if you search "Halo 3 warthog" on Google images it is the first thing that comes up. Also this set does not have a good theme. You should either do a halo set or a miscellaneous set, but don't combine the two. Also if you upload a logo or anything involving a video game it is probably copyrighted, so you should state, either in the set description or the icon description, that you do not own the game or the think from the game you used in the icons.
I have one last piece of advice, by releasing under public domain, you allow people to use this for legal purposes. Including commercial purposes, which unless you work for bungie or 343 Industries you don't have permission do so with the Halo icons.
