Name: Cloudchaser
Great name! Cloud- and -chaser aren't used often! Has a great ring to it too :3 8/10
Rank: Warrior
Nice! Most go to Leaders, or some other special rank 9/10
Clan: Windclan
Yay! The least common clan :D 9/10
Age: 25 moons
Alright, sorta young like most. 5/10
Personality: Quiet, observant, quick-witted
Wow, the personality fits together well! It's also not too complicated or has too many like others. Quite a few OC's seem to be quiet though. Maybe some flaws. 8/10
Appearance: Black and White tom with Amber eyes
Alright, this is a good appearance! The white on his pelt does make it look like clouds I would imagine! Amber eyes aren't rare, but most go for uncommon colors like blue or green! Not too unique, but cats don't all have special markings. 8/10
Family: Maplebird (mother, alive) Nightstone (father, status unknown)
And the mother lives! Maplebird is an awesome name too, though the prefix Night is pretty common. By the names, I think their pelts would be similar to Cloudchaser's too, which is good. 8/10
Backstory: As a kit, Cloudchaser was always in the background. He didn't like gathering attention to himself, and would spend his days dreaming about what lied beyond the camp. One day, his father went missing after a failed ambush on Riverclan, and was never seen again. This pushed Cloudchaser to become aware of everything that is around him, making him observant to the point of paranoia. He got his warrior name due to his ability to chase down a rouge cat that was eating all the prey in the area.
Awesome! Most toms are proud and arrogant, so it's cool that he has a more introvert personality. Nightstone being missing is a great, unique twist, as most parents just die. It's also nice that he has a reason to be observant, most traits come out of the blue. Paranoia is pretty unique too! And a reason behind his name is neat :3
18/20Physical abilities: Agile and able to quickly spot out anything odd in a certain place
I see agility a lot, but not being observant :3 3/5
Physical disabilities: Not extremely strong and only relies on speed
Nice way to compensate!
4/5
Altogether you got...
80/90!
I actually really loved this OC :D
