The base for Aquila is 30mm.
The thigh gap is visible in the 360 rotation of Aquila as well. As it says in the review, though, it actually isn't that bad of a gap. It's pretty well set along the line of where the tassels fall, and If you are the sort of modeler who wants every join to be completely invisible, its actually very easy to fill. It actually feels smaller than it looks, if that makes any sense.
The sword pommel may be bent in some cases when you receive the model. Thankfully this is relatively easy to fix, here's a quick rundown if you aren't as familiar with resin models:
- Run it under some hot water
- Bend it back to straight
- Let it cool
Tap water is usually hot enough for this process. You can either let it cool on its own or dip it in some cold water to "set" it if you prefer. The resin isn't like putty (or plastic) -- its isn't very impressionable when heated, just easier to bend, so no need to worry about fingerprints or anything. If you run into any difficulty once you have the figures, let us know, though!
