Steve, that was really nice. I can't add much to what all these guys have said. I agree, keep that nice, laid-back feeling with space between notes -- don't succumb to overplaying like I sometimes do.
Vibrato is key to distinctive blues playing. Every accomplished player has his/her own vibrato style, so it's good to find one that works for you and get comfortable with it. It's also good to learn and fast and a slower vibrato, but that will come with time.
Your bends sound great. Good to keep in mind that half tone bends as well as full-step bends work nicely, especially in minor progressions.
You got a nice, clean, spacious sound on your first recording. Great stuff.
