@mag I think the fox is lovely but I have to disagree with your husband (sorry Mr Mag!), I preferred the bear. I think the fact that the hedgehog and bear are different species would become clearer in the coloured version and I think for me the fox feels a teeny tiny bit menacing, it might be the pointy teeth or possibly just the associations of sneaky foxes in picture books. He is really lovely and beautifully drawn, he'd definitely be a great character to draw more of. But for me personally for this image it reads more clearly with the bear because she looks warmer/more cuddly/more likely to help/ less likely to be a bit sneaky!
I really love both images, your characters are blooming adorable! Just want to give your hedgehog a (prickly!) hug! So cute! You should definitely submit both if you can! Xx
