I can't even decide which one is my favourite. Probably all three of them, but I extra like the V's sleekness. Do they also walk only on the 2 last phalanges of their toes, or is this one depicted in mid-step? I have also noticed they have a reduced first toe, probably an adaptation to running.
Considering the iris colouration, is it tied to the morphotype somehow, and what are possible colours? This G specimen appears to have green irises, while Zekra has purplish ones.
Overall, they all would be fun in a foursome indeed, with lots of opportunities of set roles and role reversals altogether ;>

Heh, thanks. Yep, the v-types walk on their last two phalanges. It's probably not well-visible, but their first phalanges also lack padding. The first toe is indeed reduced, with the lowered mobility of the foot it's pretty much non-prehensile. The tail is also much stiffer, giving the v-types the reputation of being clumsy.
Pff, just make sure not to pass out from exhaustion.
Those are meant to be the possible colours, with the g-type showing the lowest and the v-type the highest frequency, while the r-type has the average colouration. There is also the option of less saturation up to a cool grey.

Thinking back on this species now whats the deal with the telekinesis? How does it work and what are the limitations?

The deal with the telekinesis is that some species do possess metaphysical abilities, like telepathy, pyrokinesis and others (A to Z is far from being hard science fiction, after all). Those abilities require specific organs to be present. Limitations for telekinesis are the size of objects (can't lift too heavy ones, can't focus on too-small ones) and the range it can be used. There was a brief explanation of the workings in episode 2, but a more in-depth exploration of it is actually an important part of future episodes and I would prefer not to put up massive spoilers in public comments.
