Ahoi!
Been working on a model of the Hylean Shield from the Zelda series as a way to help me learn Blender. I have thus far been able to make the edging via Bezier Curves, but have been trying to work with the general front face of it for what seems like a ridiculous amount of time :< What I have right now I am kind of happy with, it was created via selecting the inner vertices of the frame and hitting F, then a series of smoothing modifiers. The only issue now is that it is a whole face and whenever I try to implant the triforce and metallic squiggly (as shown in the link below) the face plate gets distorted all over again with fun new angles etc. From what I have seen Blender is such a ridiculously powerful tool and I know there is a simpler way of doing this, any help at all will be greatly appreciated, thank you!
Here are the clearer pictures:
