Good spot. The wings are tiny! A321 has the same wing as the A320 and A319, which is why it's somewhat range limited without the additional fuel tanks on the LR or XLR. Same wings, same fuel, despite needing more. Engines on the neo are much bigger than the ceo, and also mounted somewhat more forward.From the angle the wings look tiny and couldn't support that plane size let alone the big engine which looks disproportionate
Same features on the B737 max versus NG, and between the B737-9/10 and -8.
