So here is my first attempt at a real drawing on Photoshop using a tablet. Hopefully you guys can give me some advice on how to improve. Im not studying art, just enjoy it and want to get better at realistic looking concept art. So far been drawing woman mostly with a reference.

The parts I do not like here are the skin tone, had trouble picking the tone and once I realized it was off I had done a lot.

I had no idea how to build the hair correctly or choose a real looking blond color, so it looks rushed cause I kind of just wanted to finish at that point.

Also the jacket and shirt are pretty bad. Anyways those are the parts I had trouble with and done really like, but hopefully you guys can give me some input and advice, maybe a link that explains the steps in general etc.
Thanks!
