Well, the first thing I notice is that you didn't even bother to capitalize your thread title, which is off-putting and makes you look lazy to start with.
The top banner... I don't really like it. The text clashes with the background, and the Lugia images have rough edges.
Why does the "hack of" part need to be in a spoiler? That just seems like a waste of time, especially since it's
in the title.
The storyline... this is full of grammatical errors, isn't very original, and once again you don't capitalize proper nouns. I'm assuming Ash is a person, so his name needs a capital A.
As for features...
First off, CAPITALIZE THINGS.
-have a girlfriend [
Yay? What does she do?]
-new gyms [
Obviously, if it's set in a new region.]
-new o/w sprites
-rival is you sister [
Your sister.]
-your dad is ash who is a gym leader [
How original.]
-new cities/towns/routes/gyms/houses [
You just said gyms.]
-new world
-new Pokemon
-all new evil team (team inferno) [
Yeah, you just told us that.]
-you have two choices between looks(always a guy) (possible? you tell me)[
Huh? Tell you what's possible? This doesn't really make sense.]
-Two count em two rivals! (ones your sister another is my secret) [
How is one your secret? You just said that one is your sister and the other is your best friend.]
The maps are... eh. Nothing spectacular.

This one bothers me. Wtf is with this weird pathway? It looks like one of those ledges you jump down and can't get back up.
Oh my god, please tell me this is a joke. This is hideous. The palettes... just no. I'd rather let my pokemon die than go in there.
Really, this gives a bad impression like you don't care enough to make your thread look decent. Why should I care enough to play your hack when you can't even bother to take an extra 5 minutes to spell check and use correct grammar?
