The spikes are going to be removed. Even if they are small i guess some players will cry-out-loud about their shots not being hit by shooting the thin spikes.
Also, if it is too insect like - please share a concept idea of what to make instead? Don't want to finish texturing this model then be thrown into the trash just because is too 'insectoid'.
Eitherway: First attempt in texturing on Blender: https://p3d.in/29oI0
