Obviously it's up to you, but I'd like to ask you to not make a new species. If you haven't noticed, there's a large overabundance of new races, most made by new players. Please, consider (that is, you probably should be) using a race that's already been created for your first characters, and you can revisit this idea when you have more experience in the Star Army universe. This way, you'll know better how to approach the full cyborg idea. This should really apply for everyone thinking of making a new species: get an idea of how things go first, then you can think about making a new race.
