Nice stuff. I blow glass too. Judging from some of the responses to your art, it looks like there are people who should know that it's not hard to get started as a glassblower.
I was on vacation and wandered into a glass studio where they were giving demonstrations. I was knocked out by the whole process and immediately decided that whatever it took, I was gonna try it myself. It was like being kid and seeing somebody having fun drawing with crayons. I hadda try it!
Most public glass studios, and there are more of them out there than you may think, offer inexpensive "experience glassblowing" sessions. They give u some instruction, and actually let u try your hand at it.
Just fire up your search engine. Use these terms in the search window:
glass blowing art lessons (nearest large city)
And you're likely to find a few local glass studios that offer instruction.
The first lesson usually costs 30-60 bucks.
There are a few different types of "glassblowing" (some requiring no blowing at all). Flamework, Offhand, Casting, Slumping. The most common kind of bongs are Flameworked. However, awesome peices can be produced by the offhand method too.
One word of caution, Glass can be very addictive. It's an awesome medium.
