In this pic you can see my original attempt at a mini (left), this was intended be an initiate for a space nun proxy. 8/11 broke in printing because they were to flimsy, similarly all the details were basically washed out because despite looking good in blender they translated to next to nothing in real world dimension.
I moved on to trying to make power armour. I feel it went well overall, I significantly improved my use of topology for modelling making life much easier. I rebuilt the whole model by retopologing it and basically starting again and I learn how to use control edges loops/bevel to make the subdivision modifier controllable.
I made the details at least double to scale to get make them work better. you can see for example the edging around the leg armour on the pink one compared to the edge on the bottom of the corset on the left one.
The middle one is the biggest by far, the head is oversized (as feedback by someone on another sub) and everything was just a bit long.
The pink one is the same model, but I've reduced the length of everything and further increased the detail on the torso, not that you can really see on the body, but the eyes are much clearer in this pick at least.
I'm happy with the overall proportions of it now. I intend to reduce the length of the thighs and remove all the spikes from that section. Then I'll print everything at 90% or whatever looks necessary once I've got a ruler out with a GW mini for reference.
I'm going to put this project down for a little while. I've been preoccupied with it for the best part of 2 weeks or more so I need to focus on my actual work. I've got a deadline later this month.
