Welcome to AP Alex, good to see you getting out there and having a go at producing images because of threads on here.
It certainly is a good way to experiment and learn both the practicalities and technicalities of photography.
With your attempt at a silhouette I would say that you needed more outside light influencing the scene so that you could remove more detail from the subject, especially the legs as at the moment I would call that a partial silhouette at the best.
As for this part of your post ---
--- I really don't know what you mean, would you care to elaborate on it.
Contact me directly by PM if you like.
