Bit of an update because I don't want to shove all this into a wallpaper description and and make it look important.
Regarding these contests: I don't think I'll actually be submitting any wallpapers I make for them, just kind of using them for ideas.
Regarding the size change: sheer, unadulterated, laziness. I simply don't want to wait the additional ~10 seconds for a filter to.. "filter" a 2560x1440 wallpaper. If you are one of the probably very few people that have a 2560x1440 resolution monitor, you can always ask me to resize a wallpaper to that size. I like to think of myself as a nice guy.
Regarding the lack of updates: it's not anyone really reads these anyway.
Until next time, go about whatever you were doing before you wasted your time reading this.
