I like the forest a lot better now. The irregularity of the forest along with the texture are good. I might have to ste....borrow that later.

As for style, style relies on the technique that you use, and these techniques get refined as you use them and choose ones that you like the best. Your own style will start to show once you have modified your initial techniques and learn other methods and made them your own.

Personally I think you are starting to show already.
