But if we are talking about only if the pokemon looks cool then overall i would say they are fine with a few big stinkers like Ekans, Ivy and Venusaur, Charizard, Mew, Golem and the mirrored ones.
Something interesting to point out is how more static they look in their pose, reminds me of the modern lifeless 3d models standing still, which makes sense as these are their first appearance so being more standard makes sense, but from Blue Version forwards sprites tended to show much more energy and movement (except yellow which was anime garbage). If only we get something like a Blue Version for the models some day.
