ok did some "practicing" on AA and ... well goofing around i got this.. mind the colors I'm going to change them ^^ only for testing.
There's no AA in this one, yet. In my example, the two intermediate colors between orange and tan are being used to AA the drips (I actually overdid it, so it's a bit blurry - one intermediate color would have sufficed in this case). That said, AA is only really recommended for diagonals. Both of your images are constructed amost entirely out of right-angles, so strictly speaking, you may not need it.
Search the forum for useful anti-aliasing advice, that's how I learned.
