I hope you like them!
The stripey markings aren’t as difficult to draw as they may appear. Use pen tool on lower opacity (like 20 or so I think it was) and do sguiggly lines where they should be on the body.
Then duplicate that layer two times and shift it slightly to the side and recolor them so you have one layer of blue, one pink and one white. I also put the pink on slightly lower opacity since I thought it was slightly too much otherwise.
