Prototyping new models

Yes, the shield leans against the leg. In Cura you can use the Support Blocker function (screenshot taken before I used it) to block the bases and apply different speed & infill settings, to reduce the print time.

I'm assuming you're making the shield come out from the leg? Otherwise all I could see as a possible issue is the tabard/skirt of the left goblin & the chin/ears. The one on the right looks like it's mostly 45-90 from zero so should be fine. You could probably cut down on the print time with some thinner bases. One thing I find with RPG's supportless stuff is that you still need infill or internal supports on the base because they have rocks & other features on their thicker bases that cause issues with no/low infill. IMO if they're going to put features on it, then their lowest points should be within 2mm of the base, so that the 5ish vertical shells cover it.
