Those look quite good, something I would buy if/when official ones are released. A couple of things however: The background image is a little distracting and can interfere with reading the chart, a small image off to one side might be better. Also the traits look like they've been randomly placed, maybe align in columns. I think if you have the 'common' traits in the same place on all sheets they would be easy to find. It could look something like this, albeit much neater:
Traits: Agile / Lumbering
Labs X, Transporters X, Tractors X
Shuttles X, <other traits here>
Otherwise looks good.
