Hey dude, would really like a drawing of my character, Thunderstorm.
I don't have a picture, as he is a fairly new, but I do have some details for you
Appearance:
Darkish grey coat, with a dark yellow mane. The mane is like Rainbow Dash's, but shorter and a little more messier. His cutie mark is a cloud with a lightning strike coming out of it. Tail is roughly the same as the mane.
Position:
Thunder sat down with his wings closed, putting on a faint smile.
Also, if you couldn't already tell, he's a stallion.
I hope this is enough information for a good picture, please tell me if you need any extra info.
