Capturing Cadence [Markers]

Note: I understand Cadence is supposedly pink, but because of my colour-blindness, I overlooked that detail when colouring her, and assumed she looked more blue than pink. Lesson learnt - It was my mistake to not use references for this picture. I've tried to correct it based on received feedback, but I can't tell if it's become any pinker than it was, so please do let me know if the corrective measures worked!

1 day later, I realise how much of a train-wreck this is :/
Colours are completely wrong, wing anatomy is way off, and the pose is way too unnatural. Might move to scraps later on if I can come up with a better one.

I decided to use this [link] as an experiment in colouring with markers.

As this is my first time, please be harsh.
