Well done, Chris ;-)

@Micki: wrt the 'bristles'. Those at the posterior part of the body are not bristles but wax secretions in hollow tube form. The wax tubes are secreted at relatively high speed. With some imagination you can actually see them grow ;-)
These tubular wax secretions are typical for all members of Dicyrtomidae.

Thanks for ID
@Frans - You're Collembola page is great resource. Thanks for sharing your knowledge on the subject.

What a great shot!
In looking at Franz Janssens' site, I'd say you're right. Look at those bristles! What equipment are you using, if you don't mind my asking? Did you take that shot through a microscope? See

I use a Nikon D80, which was pretty spendy, but my macro set up was really cheap. I use some bellows I got off ebay ($30 w/135mm lens) and a reversed 49mm lens I scrapped off my old pentax film camera (reversal ring was $8). For lighting I use a nikon sb600 flash with a homemade diffuser. With the bellows all the way extended I can get about 4:1 magnification with this set up.
