Rising Sons Primaris Marine Test Model

Well, it took a few days of printing due to misprints as well as another couple of days in order to have enough sunshine to post cure the model parts but I finally printed and assembled my first Rising Sons primaris marine.  I printed him out bigger (closer to primarch size than primaris) in order to see how the details resolved and overall I'm happy with the results.

I printed him out in pieces and assembled him as you would a normal marine but I think the next rescaled version I'll attempt to print at the "correct" size.  I do see some things that I want to change though to make sure the model will be durable enough to see play on the tabletop potentially.  You may notice that he isn't using a chainsword katana as I had many problems trying to get that to print correctly with the teeth on both sides of the sword so I switched it to a power katana instead.  I suppose that will necessitate a promotion to Lieutenant as well.  :)  Additionally I turned the sword inward for stability reasons as the separately printed parts left a rather fragile wrist; that shouldn't be an issue with the one piece model though but I would like to hear whether the sword position is better like this.

I also had a misprint where the supports weren't solid enough on the exhausts of the backpack so I took the opportunity to redo that as well since the Cyberpunk Oni symbol was too fine to survive priming printing.  I'm still not happy with the overall dimensions of the back banner though and will likely redo it again with the rescale.  I'm leaning towards using the sashimono style banner but redoing it as a traditional 2nd edition 40k T-shaped sergeant banner.  I'll have to thicken up the parts significantly as even at primarch scale (52mm to the top of the head) they're quite fragile.  I'm not sure what icon I'll use (aquilla?  raptor?  oni head?) as well and wouldn't mind some feedback on all of the above.  Here are the other pics from different angles.
