Of course!

I gave everything a label, just to be safe. All the dot points on the freckles colours is just listing where they go.
As for her outfit, you have some options!
Of course there's the one I've drawn her in so far,
a hoodie and leggings. I put the colours in the palette to make that easier.
Or there's this
Summery outfit. It's pretty simple and could look really cute.
Other than that, there's
this one! It's called her favorite, but it's not important.
The jacket doesn't have to be included! The cat ears wouldn't have to be there either, considering she has ears up there already.
All of those should have their own color palettes included! I'm leaning towards either the first one or her Summary outfit, but it's down to what you feel like drawing her in.
