Lioness sketchy headshot

Gah. My Sai expired. I feel so lost. I still use Gimp, but only for coloring. I need Sai for drawing lineart.
I am so desperate that I searched for another program, and downloaded a free program called 'MyPaint' but so far I don't like it at all. I mean, it has really nice features, being free and all, but I don't think I can work with it....It has a rather nice sketching brush though, so nI drew this little thing here...Maybe I will line and color it later...If I can get my hands on Sai again.
