So! I took another stab at those character designs and then I finalized the weapon concepts. This represents all 4 races in my game, as well as 9 of the 10 guns (I forgot one) I intend to use.
Now I move onto modelling all of this. First up will be the 4 characters, and then I'm thinking I'll model 3 of the guns, as well as 1 melee weapon that will be designed once my think-tank and I have some concepts for me to choose from.
