My favourite is also the faceless...
Don't you worry about 'copying' or have your version of an existing work...I think almost every thing has been done in PS.
In the first place you did it yourself with the PS knowlegde you have until now.
The only way to 'master' PS is to try, again and again...and then some more...
It is always refreshing to have a new member not being shy to share his work.
You also should be aware of the fact that critique on a work is always a positive way to learn...
I love discussing a shared work so please, let them come with your eventual questions.
We will advise you the best we can but keep in mind that PS artwork, like any other form of art, is subject to the taste of the individual.
