Working on skin - need some critiques please

[flackattack]

Hi everyone,

This is my first post, so hopefully i'm not breaking any forum rules. I've really be trying to practice my skin and flesh tones recently, and i'd like to get some feedback on the following practice pieces. (i've only been painting in photoshop for about six months, so please feel free to share any tips or tricks you may know)





One particular thing i'd like to get feedback on: do you think I should ditch the linework? I tend to spend a lot of time on my lines, but understand that they could be detracting from the final piece if I leave them in. Thoughts?

Thanks!
