You know some gigs would ask you for a multiple design variations so the client could pick out the one they like. As you proceed with the task there would be your favourite strong pieces and your weaker ones. Never show the latter or they WILL
strike you back!
Last weekend I've worked on character design for some unannounced game. I picked a couple of pieces I thought were really good and before sending them to client I added another one from the scraps. It was a last moment decision as the brief asked for 3 variants. Once I've got my feedback and looked into it... BAM! they chose the last minute one!
The same story happened to Frazetta as he was doing poster sketches for Stallone's movie and Sly picked the one Frank added in the last moment. In my case the client is Square and the game is something called Final Fantasy.
I dunno if it's just coincidence or Universe's sense of humor but now I need to figure out how to make this character work and make all these players happy.
