Yeah, I am leaning towards not modifying it - I don't want to make something that will only fit on a 1/48 valk without some sort of modification - it would just turn people off. That being said, I may be able to work around it somehow - maybe making two sets of leg armor - one being a little bit bulkier, that can fit the fin inside of it, and is less accurate to the lineart. The other would be slimmer, and would be accurate to the line art, but would require you to either cut off the fin altogether, to fit the armor on, or add on a new outer leg half, that doesn't have the fin. Need to think about this a little more when I'm actually building it, and I can see what kind of space is in there, and what trade offs need to be made...
