I recently downloaded Graphics Gale, and so far I love it. The simple fact that I can use layers makes me so god damn happy.
Also I'm practising anti-aliasing and dithering, along with perspective and proper shading.
I was never good with shading, so don't expect any finished works involving these techniques any time soon. I need to work on my shapes.

At least you are striving for stronger works. It is always good to practice new things to make better pieces.

of course. My stuff right now is pretty weak in my opinion, it lacks perspective and proper shading.
While I find some of it aesthetically pleasing, they could always use work.
