Clannad signatures (unfinished, need CnC)

[Manga]

CnC please, I didn't really do a lot to the signature but I believe the over all blend looks nice. I think more effects would be good but I do not know which to use.

she has the tiniest hips ever o.O
nothing's going on, but the colors are very warming, i really enjoy the red in the top left corner.

[Eralebus]

It feels very low quality, try saving it as a png-24 instead of a jpeg.
Its a nice start so far though, good background colors and simple effects (from what i can tell)

[tzp]

Try following some tuts to get some great ideas for what to add. SO many techniques to pick from! c4d, clipping masks, smudge, blur, blend, transposition, just to name a few!

Good colors though!! KIU!

[oNo]

Yah, i agree with era. Looks really LQ. I would recommend you using C4D's to fill some empty space, and make your render a little bigger. It only takes up a little part of the entire sig.
After your done with all that remember to add depth and make sure the lighting is correct.
Keep at it ♥
