Ur avatars are pretty original but they lack of quality and composition, u need to place everything correctly and combine everything toguether.
- Find HQ renders or stock and render them by yourself.
- Use ur OWN footage or take footage from other parts but that adapts to ur project.
- Never saturate too much but try to blend everything with some color. (Degrade map works pretty well in some blend mode like soft light,linear dodge or screen)
Here's a present for you it's an Avatar i made long ago for a friend it's the full project so u can see the PSD and take some tips and tricks on how i work.
Here's the PSD download link: http://www.mediafire.com/?cicdb7vwybveuws
And this is the project already saved as PNG
Take a look into the project, watch how i made thinks and try to get ideas from it. No Rip of Course do not copy the content. Be original and make it urself i'm sure u can!
