Photography/Photoshop pictures by me.
 

how can i clean up the edges?

Or get his neck to look better?

Try to blur tool first, but with low settings on opacity & try that.

Ohhh. I just tryed it, works pretty good. Thanks!

Now how to get these more realistic looking.

YIKES!!!

Jagged edges like woah!

lol yes, that's what I'm trying to get rid of!

for starters I would say take better pictures. it will make things easier. having to spend an hour trying to fix the problem with the picture in PS is not worth the time. specially when you can take as many pictures as you want with a digi cam with nearly no cost at all.

Thanks. So what would you suggest for taking better pictures? Leaving the shutter open longer, shorter, aperature bigger or smaller? I hate how my camera limits the fstop when I'm trying to make it bigger, it won't let me go very far.

More lifelike?

Color tones? Lighting? Shadows? A NECK!?
