I think the hair fits Worf as he wore it long later in the films, as for Chakoetae and Harry it's not far off but you may be right it needs to be trimmed back a little.
these are evolution test renders to get the characters right before I actually work with them, all the ground work to make them look right and the sets and stuff has to be done first which is a lot of work in itself, but unavoidable yet rewarding in the long run.
I have not yet made the morphs for the Guinan hat yet, once I make the morphs I can add the braids so they flow out of that instead of through it.
the camera is below the transporter platform it only appears they are looking up when they are looking straight ahead, data's head is cocked a little upwards for expressiveness, but his eye level is not that far off from the others.
Guinan's skin tone changes depending on how much light is being projected onto the figure, the lights in the scene are bright to find a balance that all the figures can benefit from.
all the figures went through many evolutions and versions improving after each tweeking, so for example one Data may look better then another because you're seeing the improvements in one and not the other but I posted them to show that and also show case the costume worn, Guinan's clothes are that way, I could ass a bust to the clothes but it did not seem like it was really important.
the Starfleet costumes were swapped out for another uniform later on and I textured that one got that uniform from 3d gladiators, but I added morphs to fix the trim and gave it a uv map and a texture.
