It isn't labeled imprint because 1) imprint flavorfully goes on artifacts, and 2) ability words serve to tie together cards that are mechanically and thematically connected, but whose ability isn't keyworded (chroma, kinship, battalion, domain,etc). It doesn't make sense to add the ability word If its the only appearance of that ability in the set . Adding "imprint" to this card would make no more sense than adding "elementalist" before young pyromancers ability.
conceptart.org is going to be the place to go. A lot of industry professionals post there, as well as youngbloods looking to get their feet wet. I'm going to agree with Zombie Shakespeare; you'll want some initial art for a pitch of the game to get investors. Art doesn't come free, so you'll want to start thinking about outside funding.
