Working on a idea but not sure how I should submit it

I have been at it again with my art pad. Drawing furiously once more. I sketched something up and am in the process of coloring it in but to be honest I am not sure what to do with it. Is there a way for me to submit it because I drew it in mind as a character that knows from the rift. However I am unsure of what is required for champion material.

Should I attach the picture of the original drawing?

Came up with a base for his skills here they are:

Kra'vun, Bones of the Abyss

passive - Gather of bones

Upon champion kills or assist Kra'vun gathers bones of the dead to increase his armor and magic resistance (1 kills = 2% bonus armor and magic resistance) (2 kills = 4% bonus armor and magic resistance) (3 kills = 6% bonus armor and magic resistance) (4 kills = 8% bonus armor and magic resistance) (5 kills = 10% bonus armor and magic resistance)

Q - bonesplitter - Kra'vun extends his whip to full length dealing damage in a line applying a slow to those hit by it.

rank 1 (60 + .65% ad) slow 4% rank 2 (80 + .65% ad) slow 8% rank 3 (100 + .65% ad) slow 12% rank 4 (120 + .65% ad) slow 16% rank 5 (140 + .65% ad) slow 20%

W - Rattling Kull - Passive- every third hit heals Kra'vun for the damage delt and gives a boost in movement speed. Active- releases a fear inducing cry fearing nearby enemies for 1.5 sec

rank 1 (bonus movement speed on third hit 10%) rank 2 (bonus movement speed on third hit 20%) rank 3 (bonus movement speed on third hit 30%) rank 4 (bonus movement speed on third hit 40%) rank 5 (bonus movement speed on third hit 50%)

E - Whiplash - Kra'vun lashes his whip grabbing ahold of a target and pulls himself to them stunning them breifly (stun .5 seconds)

rank 1 (60 + .75% ad) rank 2 (120 + .75% ad) rank 3 (180 + .75% ad) rank 4 (240 + .75% ad) rank 5 (300 + .75% ad)

R - Spiraling Death - Kra'vun's bones collect around him before launching himself forward is a swirling bone dealing damage to the first champion hit. And additional damage to champions below 20% hp

rank 1 (200 + .5% ad) rank 2 (250 + .5% ad) rank 3 (300 + .5% ad)
