Nice work Matt. I used to do Games Workshop (28mm) for a number of years when I was younger - through most of senior school and into the start of uni. Then I discovered guitar, and miniature painting kind of dropped off the radar! ;-)
All this stuff sat around at my folks' place for a while, then spent some time in our loft. I finally sold it a couple of years back. A 12-year-old kid got the deal of a lifetime - probably the better part of £300-worth of miniatures, mostly painted or part-painted, plus two fairly well-filled margarine tub "bits boxes" with random bits for conversions, plus several years' worth of White Dwarf and Dragon. All for £45. I could have got a whole lot more on eBay, but I thought I'd rather sell to someone who was going to get some real enjoyment out of them.
I always enjoyed the building and conversion side more than the painting side, although I got fairly good at the painting by the end. But the model-making side was always my forte. So roughly three-quarters of my figures were converted in some way or another, whether by adding standards, changing weapons or adding backpacks/satchels/webbing belts. Or sometimes more significant changes - a whole squad of guardsmen (normally armed with rifles or pistols) got various swords, cudgels, shields and other hand-to-hand weaponry instead, which entailed lots of chopping and changing of hands and arms.
On 28mm, the dimensions are deliberately a little off, because that's the Games Workshop style. Early GW models *were* to scale, but when GW changed the house style they all started looking like WWF wrestlers instead of, well, people. That tied in with the whole shift in GW approach at the same time, changing from a very dark, gothic style to a much more kiddie-friendly feel (and simplified rules accordingly). I remember TSR 25mm miniatures were pretty well to scale though.
