I really love this, like the style you chose and I like this side of Marceline. It's more shy/serious
I really like how you draw her; she looks so cute! Her personality really shines through here. Her pants look great; I have no idea what you'd call those kinds of pants. Sort of remind me of a less restrictive corset, something like that. She just looks very fit (such as in the legs) and it's an awesome look.
slkdfjdslf she looks great in your style!
I like this!
