Here are some little openions but I strongly hope that someone who is more familiar with Adobe Photoshop will hhelp you.
It will be beter if you have two different layers for the body and the head top.
select the apropriate layer and go to bevel and Emboss inblending options.
First try to get what you need from the above structure parameters
then under shading column custamize the appropriate parameters, Here mainly concentrate about the 'Angle' & 'Gloss Contour' then adjust the opasity of the Highlight and shadow or choose a mode (Normal,Softlight etc..)
Here I'll some of the quantities but I really don't knowwhether they'll suite u or not
For Body
style-Inner bevel
technique-smooth
Direction-up
size-90px
soft-16px
angle-60 (use global light)
altitude-30
Gloss contour-65in & 45out (anti aliased)
Highlight-Normal, white (255R,255G,255B) 100%opacity
Shadow-Multiply, (255R,146G,5B) 100%opacity
Sorry about the detailed information because I cannot even attach a picture of what I discussed because of my connection malfunctions so hope this will be useful
also check the defoult styles given in photoshop specially under Glass buttons & Web styles
And also search in our tutorial files for your desire and you might be able to find it.
