The muscle of her right arm is too large, and too much on one side. It should be showing on both sides of the bone, I think. Even if you went for a deformed style on that arm intentionally, it looks odd.

With that said, I like your style, where you keep no clear frame around the drawing, but let characters go outside the invisible edge of the background. Nice colours!

Mmm, I really like the saturated skintones and the reversal of negative and positive space in the background. I think in your previous image of this style, the background was a little busy and overwhelming, but by changing its complexity and the scale of the figure, the woman becomes the focus here. I agree that the bulge at the base of her forearm seems off, even though your style is obviously not naturalistic.

Background composition it´s great!
El cuello se ve muy largo, pero no desencaja tanto con el estilo del dibujo en general. Buen trabajo!!

Great work!
Mariano I love your style

This is briliant. Like it very much, nice composition colors and form, the arm doesn't disturb me that much, to me it loks rather funny than odd. Though i don't know if this was your intention or not i will just leave it at that and give you my max.
And again there has to be the little thumb to underline my wowiness about this drawing. so now I proudly present:.... the Thumb
