The helmet and shield both have a pretty shape. =D
Btw, since you followed my tutorial, I'll try to help you improve stuff on them with a few suggestions if you don't mind. Also idk if you saw ones I left at that thread, but here:
The shield is too bright on the edges, and yellow contrasts with black a lot, so you should try to neutralize both of that with AA, also, the redness inside should be a bit more variating in shade, it seems flat red when looking like this.
The blood on the sword on few points goes over the outline of the sword, you should fix that. The handle is also too bright on the left wing and too dark on the right wing, could tune that in a bit. Also that oval shape on the handle stands out a lot due to it's outline being dark on a light background.
The helmet just needs more shading , looks too flat atm.
Looking forward to see the progress :]
