I'm sure it's obvious by now, but I'm a big fan of finding the right mini for my PCs. I thought I'd take you through my thought process when it comes to picking a good representation for your character.
I almost always start with a character in mind. I'll usually come up with a handful of character concepts at once, and prior to the start of the game I'll pitch these characters to the rest of the group to see who will fill the niche role needed by the rest of the party.
This morning I had an idea for a character who is a zoologist (cryptozoologist?) seeking to create a field guide of dangerous monsters (The Liber Monstrum). Of course, to properly document these creatures he'll has to seek out, fight, and take specimens. Think a combination of Indiana Jones, John Audubon, and a healthy smattering of Steve Irwin (Crikey! That Tarasque's angry!).
Once you have a character concept you start getting ideas of how your character looks, their class, and the tools you want them to use. You probably have an idea of their personality and role as well. So whether or not they'd be a taciturn sneaky rogue, as opposed to a jubilant swashbuckling rogue. Visualizing you character informs what kind of miniature you want, as well as the personality you hope it portrays.
With my "adventuring naturalist" summary in mind I break down a few things I'd like to see about the mini:
* Human, Dwarf, or possibly Elf
* Seems likely to be a wizard or ranger
* A rugged but scholarly look (preferably with a book)
* Also in my mind is that the mini shouldn't be overly aggressive. No charging into battle or screaming battle cries.
If I know the class I want to play I'll usually also list armor & shields among the things I want to see. I don't usually list weapons as deal breakers for my minis, since weapon swaps are a relatively simple modification.
So with these broad ideas in mind I go about my search. If I don't have a mini in mind already I tend to start looking in one of two places: Reaper's Figure Finder, and Privateer Press. I like these two because they're about the same scale, and they both put out good high detailed metal minis.Privateer Press has a strong steampunk/technology vibe, but that can be worked around.
After a cursory search I found a few possibilities.
For a more ranger-esque character this guy would fit the bill. I'm not as keen on his hair, but I'm no stranger to adding a hat to a mini either. It isn't my first choice, but a decent option.
For the record, I'd probably choose either the "Egon" mini of the Privateer Press mini. My decision would be made after chatting with my fellow players, and brainstorming bits about our characters. I see the Egon mini as being a character at the start of their expedition, whereas the PP mini would be a veteran explorer.
Once you pick your mini you can modify, convert, and paint to fit your exact ideals. I always use minis to help me get a feel for my character, so the closer I can get to my vision, the closer I feel to the character. Hope this helps you the next time you need to find the right avatar for your tabletop character.
