SSimpossible's Drawing Pad/Sketchbook

Hello, everyone! Since I’ve joined Blender Artists, I’ve never actually posted anything in this category of the forum; I thought that was kind of strange, since I’ve been drawing for a lot longer than I’ve been doing CG Artwork, so I’ve decided to start this thread. Critique is welcome. Here is the first image (more’ll come later). My major critique on this one is that the sun’s rays are too crooked (it’s also sort of difficult to change it because of the way I chose to do the rays). What do you think?

Oops. The image wouldn’t upload. Not sure why; it’s a png, it’s not that big, and it’s black and white. Well, here’s a link: http://1.bp.blogspot.com/_vfkyomEnc-E/TJvxOxi-ViI/AAAAAAAAAU4/jxcLRBZzAaM/s1600/Tree_Sunset.png
