There's nothing to be jealous about - all you really need to do is to just go for it.At the time where I started doodling, I also was very afraid of doing backgrounds and actually never intended to do them. But one day I just thought : '...why?' and then started practicing. In my opinion it's just really a matter of just trying it and be open to learn new things. But the most important thing : Be open to accepts mistakes and such, because after all it's a process of developing as an illustrator. Even right now I think that my sceneries are quite bad and there's so much to learn until one day I can consider them as good - so just don't worry and just go for it. : >
