Where should I start Game Dev now?

So, I have CS degree, MMO dev experience in a native language (think WoW and its scripting language (LUA?), except standalone,) and a lot of 2D games developed in C# XNA.

I want to move to C++ but I'm not sure where to start. At the moment I'm looking at GameDev.net.

I've been in an applied comp sci (IE: technical programming) for the past 2 years, but I realize I want to design and create good games; not necessary "build" them. I don't mind getting my hands dirty with code (have some experience with C++), but my main objective is definitely to create good games. I am even artistic and wish to implement my artistic visions into my games.

Have I been taking the wrong approach? Have I been wasting my time with this pure low level programming?
