Welcome aboard ArtWar! And don't feel down about joining in, a big part of what Marc has put together here is about learning, growing and building a community! So keep at it! Stick around and browse the other forums too and check out all the fun stuff!.
Regarding the silhouettes, I think that going with 4 was a solid choice, it and 10 were probably the most fun, and that circle has a lot of symbolic links with the sun which helps. Personally I like 10 more. And I am talking about your very first post btw.
I would recommend trying to develop the big ol halo, really makes for a more interesting silhouette than what you have in the most recent post. The most recent just kind of reads like "just a woman"
Keep at it! I look forward to seeing more.
