the samus looks surprisingly accurate for its scale and complexity, but I’m a bit iffy on the EMMI. The size and colors are good, but the open studs are a bit strange considering how smooth the EMMI usually is.
The Samus figure is perfect, I’d argue it’s better than a minifigure because you can get it into the more dynamic poses that she normally does in gameplay. Like Cordax said, the Emmi is a bit iffy with the rough stuff, but I think you could fix it with just some tiles on the upper legs and lower arms (those are the only parts where it seems to be a problem). Good job on this!
I think it would look pretty good as a display but all of the one stud connections might be fragile for play. You could probably make some really cool scenes from the game using the figures though
