i really enjoy some of the artwork posted but personally my favourite artists are berthe morisot, pierre auguste renoir, and camille pissaro. i have so much love for the impressionist era and that specific style of painting, and its basically the era i've studied the most and the style i find my own personal painting style echo. Frida Kahlo is also one of my favourites, she's incredibly skilled and talented and i admire her as a person as well. barbara kruger's pretty interesting as well.
There was also an exhibit i saw at a gallery once for an artist whose name i can't remember anymore but basically he made this incredible sculptures of the human form and such out of completely unexpected material, giving his sculptures an eerie, decomposed look and it was absolutely amazing what the guy did.
