Nice work on this one. Your stippling is consistent and confident across the whole piece, so continuity isn't actually your problem. What you're feeling is the lack of a clear focal point. The windmill should be the star, but right now it's rendered in the same dense blacks as the bushes on either side, so the eye lands on it and immediately slides off to the equally dark masses around it. Nothing tells you where to look. Two things would fix most of it. First, push the windmill darker and crisper than everything else, or keep its neighbors lighter, so it stands out by contrast. Reserve your heaviest blacks for the subject. Second, vary your stipple density: let the sky breathe with sparse dots, keep the distant field light and airy, and save the dense texture for the foreground and the windmill. That alone will create depth and calm the read. The hills-running-into-bushes clash you noticed is the same issue: the shapes merge because they share the same darkness. Lightening those transitions or leaving a sliver of paper between them will let them separate. Good eye spotting that something was off, by the way, that's the best way to learn | Artwod Feedback
