good job, but way too easy to get through. I can't get any of MY art forms to be accepted but I can just keep doing all the lowest options and then resell until I get a bit, then I just go to the academy, draw porn for a while (hiring girls privately when available and switch back when needed.) I go back and draw up something new right after the salon happens then spend some time chatting to learn new techniques. I usually keep my best-so-far painting (by price) tucked away so I can submit it and then sell for mint. In about a half hour, I was making "Masterpieces" with my stats maxed out selling realism drawings for thousands after having them place first so many times. I haven't figured out how to unlock the other drawing tools but I really don't need to.
Try to mix in some life stuff as well and some more options (like attending other musical or party events). Allow for walks to locations for ideas and make painting/drawing make expression go down instead to simulate running out of ideas. Allow for more complex relationships with various characters and more chat options. Also, an artist can be many things, perhaps things like making music or inventing could be included somehow.
It's a pretty nice start but only a start.
