This is a small fly (~4mm long, head certainly <1mm wide) with lovely rainbow eyes. Not sure if this is a small one of the 'long legged' flies, and I doubt anyone can confirm from the portrait!
Stack of around 120 images with Nikon 10x objective on OM bellows at around 1/3 extension. Stacked in Tufuse with one sub-stack for the left antenna. The right antenna was at a very dodgy angle and I do not have it in focus at all..
Possibly due to the slight crop causing a squarish ratio on the image I had to use quite a bit of jpeg compression to squeeze this under 200kb. (Possibly also something to do with the colour/complexity of the eyes on this lady!)
Here's a 100% crop from the right eye:
