Tried to catch the feel of the game portraits, not sure if I 100% succeded, but they do work for any fantasy characters you'd care to make, tried to tag both races and classes, so you can try out those with some cool effects.

For the record, in case you'd care to make some portraits for the game itself, maybe for a playthrough of the IWD2 Enhanced Edition mod that recently came out, the large ones are supposed to be 208x328, but it's ill advised you make them that small, you might want to make them 832x1312 and then just make them 25% size to fit in game. The small portraits are supposed to be 42x42, by the way, so you will need to crop the pictures quite a bit.

Enjoy!
