Good job, sticking with what you like. XD *thumbs up* Though I've never seen/played/been a fan of Robotech, I don't think a nice wall is possible without liking the subject. Needless to say, this is a nice wall. Those whisps from the planet that looks like stylised wind, or atmosphere, are awesome~<3
I think the bot could use a little sharpening, but... it's not like it's ugly blurry or anything. It's just that in close contrast with the (sharp) distant stars like that, it looks a bit strange.
Anyways, rock on, solid skills. :)
