It's not pointless.
With your same concept, then ALL artwork is pointless too, since it has a text describing what happens.
For me (and probably a lot others too), the character customization is part of the fun.
It would be cool to have all the body variants and clothes, but it will take a huge lot of work. Not difficult per se, but extremely time consuming (and Alis has already so much on his plate, that is missing some parts on pictures, like hands lol)
If anything -speaking of artwork-, the only thing that kinda bothers me is the lack of consistency between descriptions, text and pics.
For example, while Hiro seems to be small sized, the pics depict him with quite the schlong.
Urka says "you're quite packed for a human", which sounds silly considering the Hiro is at best just average. Or the ghost Lady, which is described has (basically like sitting on a eggplant", is actually much smaller than Hiro (can be seen in ghost possession) which as said should be average (and that because the "average" size was added recently, previously was from small to tiny)
On the other side, while gobbos suppossedly have "a log", they're only 8-9 inches, for example.
Nothing game-killer, but still something worth noting.
