Aw, thank you! The sylveon girl is a mixed medium piece. I started with pencil then went over it with super thin colored pencils. After that, i began coloring with a combination of said colored pencils and watercolor pencils, which I only used by way of dipping the went paintbrush directly into the pencil nib. I then went in (and will continue to) and did some minor touch ups with Photoshop. :). All that said, the very first version I posted here did use markers, so you're not entirely wrong either!
Also, hehehehe, I hate to tell you this because it's going to bother you, but your missing one Fairy from the collage. ;)
And yes, pixel commissions are open. PM me or find me on DA (username: Douxette - I have even more pixel work there) if you want details! (。'▽'。)♡
