3D-project ideas

Yo everybody, I'm thinking of making a new project once again, and would like to hear some ideas from other people any sort of ideas that could relate with these 2 factions I'm creating. Both alien races and differences are: [right] Groganian: ferocious & sinister creatures (Tyranid, zerg type) [left] Space Wraith: technologically highly advanced warriors purging the unclean (Protoss type) to check their type properly check my gallery :) So post up and say whatever would come to mind, some specific details and such. Then with those ideas I'll be making more units for both factions then theres bigger possibility to turn them inside the RTS game I'm planning to make someday in the future :DYo everybody, I'm thinking of making a new project once again, and would like to hear some ideas from other people any sort of ideas that could relate with these 2 factions I'm creating.
