Whoa! Lines are so jaggy, but I can't blame ya. Though it's because you're using older photoshops and only CS+ have the vector outlines you'll need. You need a pen tool or use an Illustrator. -^^-

I really love the background here because it's so flowy. Though about the colors on Riku well it seems more painted not that I would consider vectored actually sorry.

Gee, thanks a lot.

Firstly, in regards to what moonescape said. Yes the lines in places are jagged, but they aren't as bad as moonescape made it seem.

I think you did a good job, especially using the older versions of photoshop. (I use elements myself ) I like how you made the wallpaper. Yes, Riku does look painted and not vectored. But, being vectored would make Riku look...weird, I'd think. You can't get the subtle changes with vectoring like you can with a painted look. So I like how Riku looks as he is!
As for the bg, it's awesome- looks like a real sky. Good job all around.

Thank you!

nice work! a large well-made riku wall is a rarity.
