Lady in Red

I have been pushing myself artwise lately. I feel like I want to finish my art too quickly. I'm trying to stop myself and take more time and try things I haven't done before or things I really want to do but didn't have the guts to do (because I have the feeling I'm not good enough to achieve it).
I'm trying to get myself past those barriers because I think if I do that it will make me a better artist and open new possibilities for me.
It took ages but I wanted to prove to myself I could paint and airbrush realistically if I just took the time. This is the result.
