Great use of color,very warm and friendly,, I love the highlights but to go with the previous critique things are a bit flat here that really should not be.
One of the things that does this is that the darkness of the hat being so uniform messes with the sense of depth and does not read as strongly as 'shadows' and 'darkness' as it could. It feels a bit more like just a flat brown-ness.
Your choice of framing shape while visually interesting reads a lot more as a flat card stock then a depth that things are happening in.
the collar of the coat also seems a little weird to me but I'm not sure why. maybe the angle is a bit off somehow but not sure.
Otherwise this is great, love the character and first impression reads really well, I had to dig in to catch up anything to critique.
