Dont feel dissapointed, you\'ll only get yourself stressed (trust me, it happens)
You need to highlight on the flesh and clothes. IMO you have tabletop standard, probably around a 4-5 score. If you start highlighting you will raise this to over 5 easily, on th clothes take the brown you have painted it with and mix it 50/50 with bleached bone, water it down then paint this onto the raised areas of the cloth. Then take bleached bone watered down and add this to the edge of the clothing.
Also paint the eyes white and add black dots, this may be easier to do if you dont paint over the primer on the eyes, so you can either just add white or black.
The flesh also need highlighting, simply so as stated on the clothes but use flesh shade instead of browns.
Hope this hels, and you understand it, read through the articles on this site, and keep posting in the forums as these will be main sources of help.
