Alright, I also added a soft glow to the person, so that it matches the background lighting to make it look a bit more realistic :P
<---- Colors: Eh, make the grass darker green, the dogs black except for their chin aannnd that's it. Background Color: Keep it.
Making the dogs black turned out to be extremely difficult without making them look terrible, but I did the best I could. Sorry if it's not as you wanted it :L
Image you want photoshopped: Any certain colors you want it to be?: The shirt can be blue, the slimes can be green, and the ground can be pale.(Or you can include no ground, what ever you choose) Backround color?: Blue Thank you ;3
Sorry, I forgot about this for a while, then remembered to do it XD Apologies for the long wait :L Anyway, here you go:
