Are you using Cardbaord for the Armor pieces? If so, was just wondering. you can do it with cardboard, however. another way, costs the same and gives you a better outcome (imo) is using Foamies' Your progress is nice im not say urs is bad, just you get mroe defined detailing with foamies and more depth, cause you can add onto other pieces ect. i like how you are forming the back caster. Thats one thing i have yet to get around to do, Looks good. Also, another thing i would say would, give the Bio more shading, aka around the crown area give the creases more dark shading make it look... well more badass. you can use airbrush or spray paint. just make sure u tape off the areas u dont want hit with overspray.
thats about all u need really and my little advice. Bio, and if more time try Foamies.. everything else looks good. Gl. ill Ttyl.
here's my costume.. using Foamies and other assorted items i made. dreads ect.
The Bio is a bit small isn't? nice job on the chest armour, I recommend u use foamies or foamboard for your armour bits and bobs. Will be alot stronger than cardboard as it probably wont last as long. But still looks good mate.
Foamies would work well. If you can find Sintra (foamed PVC plastic), that would be an even better choice. You can heat Sintra up, like in a boiling pan of water on the stove, then shape it to fit and then cool it down. It'll keep its shape. I did several pieces of my original armor using this method.
