Does my avatar look like me?

I wanted to make my avatar look exactly like me. Is that really possible? I knew in advance that it is quite impossible to make it exact. May be, but I am not sure as I am a newbie in the second life. Someone told me in-world that there are people who can make money out of it. But as far as I started dealing with my appearnce, I discovered that it is a real challenge. My first trial was in vain. I ended up by making a strange face. When I showed the modified avatar to my wife, she made fun of me. She said that I am not that ugly!!! (I am not sure). She gave me then some help trying to make my avatar's appearance closer to me in real life. It took several attempts and some time to know how to deal with the features. I surely know now much more than before. The more you deal with it the more you discover more and you get more skills in SL. I also managed to do free shopping and discover landbox... It is a real and nice experience. I once was somehow frastrated when I got into an island to do some free shopping and found out that I lost my appearnce and became a ghost. I can't even see myself. I became a mere white smoke that can move under my control. What have I done? And how can I get back to my initial state. The problem was solved once I got in the SL the next time. But I don't know haow that happened and why. It is something I am trying to dicover.

I do still have two problems with my avatar. The first has to do with my skin color. I haven't managed to get the right one though I tried the options we have while changing appearnace. The second is my hair. I prefer to be hairless because I find it closer. The job hasn't finished yet; I do still have to work with my second self to make look better.

I would here cordially thank all the poeple who offered me help in-world. They are really nice and helpful.
