I have a few suggestions. Set render eg, Mythalogical creatures ( from games ) could be interesting. Set colours, havnt seen a set colour in a while ( not that im around much ) set style, grunge, brushing only , smuge ect... Set tools ( using GR's own artists select a set or a few sets of tools eg, brushes , patters, renders , c4ds stocks ect..... use only those tools provided in a pack ( maybe consider for 56kers, leaving the items seperate for easy d/l ) Concept brief, like when a contest is run for another site, look for a spacific out come ( obviously not too spacific) and see what that artist come up with from that spacific brief. Action sigs, Using only renders or stocks of game characters in action, eg doing somthing from game play. Yeah thats all i can be bothered suggesting maybe you can keep some in mind, i dont realy create anymore now that i work all day so i doubt i'll contribute.
