I just finished my latest pile of Reaper miniatures (ignore the Wizkids Manticore on the right) and thought it would be fun to go through my collection by sculptor.
Reaper is my go-to minis brand because it's the only one you can semi-reliably find in game stores outside the usual spread of Games Workshop/5E/Marvel/Star Wars/maybe Infinity. Stores have to stock what moves, and indie miniatures are a big risk. I've never found anywhere that carried Reaper metals so I've only tried the plastics.
They've got the typical flaws associated with plastic figures. Bent weapons that won't stay straight even after multiple boiling/ice baths, mold lines that inevitably cut across the most detailed parts of the figure and can't be removed without gouging out facial features, occasional quality control issues that look like someone doodled on the flat surfaces of the mini with a scalpel... Price of doing business. In exchange you get cheap, durable figures (I dropped several to no ill-effect while photographing for this post) and a huge variety of characters and monsters. The bulk of the figures are fantasy but they also offer smaller pulp, modern and sci-fi lines.
This will be a non-representative sample of each sculptor's work, since I just buy and paint whatever looks fun. I've been painting miniatures on and off for about nine months now, so this is how the models look in the hands of a beginner-to-middling painter.
