Painting Update - Flannel headache

We're going to call that shirt done; at least for now. Getting a headache from focusing so intently in lines. It looks good as is, but the actual shirt has like 4 more line layers to tackle... We will pretend they don't exist, eh? It'll be a while before I work with a flannel pattern again; it really helps with making structure pop, but it is such a pain in the ass... no wonder in cartoons, flannel is often just a static layer.

That cuff on the left is bugging me, now that I'm looking at the image zoomed out. I don't want to look at the ref photo again tonight to compare it, but the shadows feel off between it and the sleeve.
