Spoopy Haunted Mansion - trial run

When I get this all sorted and done, i'm hoping to shrink the size to it's a max of 1000x1500 or 2000. instead of a whopping 3000. . -.

So, main story is.
Once there was a mansion which housed all kind of ghost and dark poke'mon. People from all over the region would come see these ghost play with each other and even the guest who came to visit. Humans and poke'mon who visited this mansion always left with a bright smile and memories to last a lifetime.

Once upon a time, Trainers would come to visit to capture them against their will without the mansion owners permission. On a rare occasion the owner would allow some of the ghost poke'mon to be adopted out to guests who showed a true bond with that poke'mon. Some people who were denied of adopting these special poke'mon often caused mayhem until they got what they wanted. Soon groups of gangs would come steal the poke'mon which upset the other poke'mon as they had to watch their friends and family members beaten and captured by a strange humans who they thought they could trust. The mansion owner did not know much of this until one day during their feeding before guest would arrive he noticed they were quite skittish even around the man who they've known for years. He started to notice that there are less poke'mon that show up each day. The man was never sure of why they would leave or just vanish but he assumed they just wanted to live outside of the mansion which he didn't mind at all as long as they were safe and hope they would return one day. But the poke'mon never returned.

Days of these acts of gangs stealing poke'mon went on for weeks. The poke'mon barley showed themselves at let alone come near the mansion owner. There were only a handful of poke'mon left in the mansion. There were barley any guess either. Some days nobody would come it but the man to put out for the poke'mon. One day he left a mass of food for them in a pile, As he was leaving he sent out his poke'mon and asked them to stay in the mansion to keep the other poke'mon company while he was away. Be he never returned. The man passed away 2 weeks later due to a break into his own home and was murdered, by a gang says a witness. The same gang that always snuck into his mansion to steal some of his poke'mon.

2 nights later it was a planned break it for a big haul. To steal all of his poke'mon and leave nothing behind. Not even the doors.
But when the men returned to steal the poke'mon, the poke'mon had a plan of their own. To retaliate against the bad men who have hurt them and taken their friends. It was man v.s. beast. Lives were lost of both sides but the poke'mon who ruled this mansion have claim their home back and this time for good.  

"No human survivors. We will do it again if another human steps a foot into their territory. Friend or foe. All humans are not to be trusted. Not anymore. We are the soul of this place we call home. We must protect it. Even from other poke'mon if they dare threaten our family or our home. We will survive this war. There will be no peace. Or mercy."

Weeks later the poke'mon of the mansion soon ran out of food but they were too scared to leave the mansion. They either had to starve or eat the bodies of the dead gang members. Some had no problem making this choice but the mansion owner's poke'mon would of rather starve to death than to eat a human. One of the mansion owner's poke'mon was a Gengar. Gengar encouraged his teammates to eat or risk leaving the mansion and let who knows what happen to them. The bodies could supply them with food for few months and then they have to either risk it all to escape or wait for new victims to come visit.
