Brisineo is your brother? Cool! You and your bro's vectors are nifty! :3 Anyways, I'd say start with whatever works! What program do you use for vectoring?

I use a program called Corel Paint Shop Pro Photo XI. It's not the greatest, and can get on my nerves at times, but it mostly gets the job done.

Yes, Brisineo is my older bro, and I am still trying to get my vectors as good as his.

I use Inkscape for my vectoring, but it does not do well with special effects. I tried using Inkscape to make (kind of) a wallpaper HERE: http://mlpforums.com/topic/45352-beat-shock-oc-vector-experiment/#entry1070872 It didn't turn out that well for me.

That looks awesome! Yeah, I've never used inkscape before, so I wouldn't know... But anyways, I've also never used Photoshop, but I think a lot of stuff translates over to it from my program. But if you don't have anything like that, I've heard that Gimp can be a pretty good program. You might wanna try a Photoshop free trial, or something, for a more full-featured experience.

So, what kind of wallpaper are you going for?
