I did a little experiment last night in my art journal using acrylic duel paint pens for the first time! I love the way the feathers turned out. You have to shake each marker before use, that is a pain and I also did not  like the tip of these particular markers (bullet and fine tips) as I prefer the brush tip best. I purchased a couple of cheap ones to try out so I know I prefer the brush nib. I am researching what make has the best review. I think I will only use the for art journaling! :-D
