Hello. I just want to give my artistic opinion about his Champion Decription because I have started to create concept art for Tyzone.
"Standard medium build, about 5 ft 10 inches. Wears glasses and there is a hovering purple portal behind him."
-This is good, I like the originality of the glasses, and his own personal void portal : )
"Wears a golden robe"
-Erk :S I do not know why you would make gold the main color on your champ, sense other void champions have darker colors. You are trying to create a distinction between Malzahar and Tyzone, but gold is too bright for his main color, it strains the eye and is not a very appropriate color for robes.
"outlined in light purple marks."
-The light purple gilding decoration is good, but i might suggest making the purple the main color (making it lighter than malz's purple) and the markings gold.
"Has a hood that is glowing gently green."
-I do not understand this. You use a gold and purple, then you pull out another bright color like green. There is too much contrast between those three colors for me, and i don't understand why it would be glowing either. His robes and his hood would be competing for the viewers attention.
"Has blue eyes and short brown/black hair"
-Ok sounds good.
"His arms are sticking out of the robe with blue inscriptions etched onto them which glow extremely bright."
-Ugh, another item that is too bright, and it will make his figure too busy; this will strain the viewer's eyes. You have too much contrast with all the colors you have chosen for Tyzone; gold, light purple, glowing green, blue, brown/black, glowing blue. I would suggest compromising on the colors that Tyzone uses. It just feels like you just starting using random colors on him to make him interesting.
Sorry if I was harsh.
