Not quite. The -> operator basically puts the prior result in as argument number one of the next statement, so you need to create an expression who, when it has the result of :char put in position 1, returns a vector of eye color and hair color
Luckily the core library has a function (juxt) which does exactly that - given two functions makes the result of calling each on the same arguments. So you need to create a function (juxt :ec :hc) and then you need to call it by wrapping it in (). So (-> human2 :char ((juxt :eye-colour :hair-color))) There are, of course, a million other ways. Here's another which is may be easier if you aren't so used to higher order functions. (-> human2 :char (as-> sub [ (:eye-colour sub) (:hair-colour sub)])) using the "as->" idiom which basically binds a variable in the subsequent expression to the result of the prior expression in the -> (that's not really what it does but in this context you can think of it that way).
