I like your new map! i am sorry i go into criticism for it, because i haven't ever worked on an HGSS style map. But it isn't crap, that's for sure!
I guess the biggest C+C for the trainer's backsprite is a question. Is he wearing a hat?
If he is wearing a hat, then the shading makes sense, however it seems connected to his head and it is complete with sideburns.
If it's his hair, then it all around doesn't make sense, mainly the contrasting lightsources. But I'm mainly thinking it's a hat.... trying not to be insulting, here.
Your fakefishmon are both pretty simple looking, so not too much here.
Usually pokemon sprites are meant to be facing the trainer it approaches, so for Roshire, all i suggest is you move the pupil down so that its looking that general direction. It's imperitive the fakemon is aware that it is in battle.
anyway, overall you have some real high quality sprites, then again some look rather rushed... But you got some poten-ti-al!
Sprite on.
