Yea I agree with steve there about his comment for switching to ID for entertainment. I mean, yea sure there're alot of great concept artists that recently came out of the ID major, but there're also alot of great concept artists that didn't. To me, i feel like drawing people is alot more interesting than drawing products. Even though being very technical and percise is very important when it comes to entertainment, I don't think these factors are enough to make me switch over to ID.
I guess it really depends on you though, if you seriously want to be very technical and want the ability to draw like a machine, you'll probably want to switch to product then.
