On first look Entei looked really well and in a pose fit for its character(at least from the movie). However the more i look at it the more i get disappointed:
1 The front right looks bigget than the one that is closer
2 Its sprite is like with the graphics from R/S/E. The pixels are made so that is looks like is had static.
Lugia is really well made on the other hand compered to entei's. The sea guardian has the best so far i have seen. Not like the ones from the past generation.
Ho-oh, another sprite taken from the other games with no significant changes implemented to it.
R/S E FR/LG D/P PT
and finally Gyarados - the sam as wraith said except for milotic part. It has the serpent look that it actually is supposed to have. I will skip some this time:
E FR/LG D/P PT HG/SS
