I just looked at your 'Halo' signature i believe? Try match the colours in a tad more. The background (starry thing) is very bland. The halo character also needs to be blended in a little more with the character behind it. Smudge/blur, that's up to you. The lights and swirls stand out a little to much, maybe lighten them up or change the opacity. Here is SOME advice, always post on my wall if you need assistance. @Kleviso
