Rawr.

Should I make the picture of Sora and Sunao more sharper? I've been fighting with my sister now 15 minutes, and am sure that I'm getting nowhere with this if I don't ask someone else's opinion. ^__^; My sister doesn't know anything about anything, so it's hard to trust her word. x3

Andand. Is colours okay...? I love killing wp's putting much of colors in it and I don't have any sense of which colour is good with other... x3

When this is ready, I'll try to get this submitted in here... If it's good enough. >_>;

Well, the color looks fine, but if you wanted to make the color's stand out more, a simple overlay would of course fix that, as would many other things. I think it doesn't need to be any sharper, but thats my opinion. Also, it might seem more like a wallpaper if it had a title, but thats just a suggestion too.

It's not bad, the lineart is not very defined but you have crisp dark outlines around the characters which makes them stand out a lot. This is compounded by the subtle drop shadow, which you could try getting rid of. The water effect on the background is really nice.. as for the colour scheme it doesn't fit perfectly but the water matches the illustration nicely.

Mmmm I dont think the background and the image matches well... They seem a little blurry too.. If that's how you want them, make the bg less defined and match the image more and vice versa...

They look like they should be near the seas or a lake, with those fish in their hands.

I love those scans! Sukisho is just too cute :)
I think Sunao and Sora's faces are a bit too blurry, but the rest of their bodies are fine.
As for the background, the effect is very nice, but the color doesn't exactly match. Perhaps make it just a tad more blue with the hue/saturation window.
Otherwise than that, this wall is really nice. There just aren't enough Sukisho walls these days so I hope this gets accepted (and I'm sure it will ^^).
