This is my illustration for larp named Alpha Colony, when two important characters, Denarea Tridelti and future Colonel (commander of the colony) first met.
Denarea cried. Some human children bullied her, again. She knew she isn't the only, humans terrorized many inhabitants belonging to other species. But it didn't hurt less because of it. They stood around her and laughed, laughed badly and hostile.
And then a boy appeared. He had red skin and dark hair. Denarea hadn't seen him never. He looked around and when he saw what happens, he attacked the nearest human boy and throw him away. Other humans pounced on him and fought for a while, but then they finally escaped. The boy got up and sat on the ground. Suddenly Denarea uprised, run to him and kissed him on his cheek.
"What is your name?" she asked then.
"Tartrik," answered the boy. "And you?"
"Dena," said she shyly.
It was part of backstory of our characters. They are both aliens, Denarea is Dakri, the boy is Letrioc. There is only 2 years difference between them, but adult Letrioc is almost 2,5 metres tall, so he is probably taller and stronger than other species already now. About his colour, this isn´t blushing, this is his natural skin colour. But... Well, it is presumable he blushes, but it isn't visible because of this skin colour.
