I Need to do Photomanips again. I'm rusty. Just need inspiration

I've been on fire art wise. I'm also in a good mood albeit a confused one. I have to mention, I'm contemplating doing stock, using chroma-key. I'm not sure what kind of software I'd need, It's hard for mac users (picky ones like me) to find the right software. and you might see some photography in general from me yet.

I'm driven and I'm Mad. My anger will fuel my art!
