Drawing ; painting...

Tomorrow is the Art examination. We need to complete 3 preparatory work before the day. I've been working on them this few days. I just done with my third preparatory work piece. It looks so dull... I try adding some green to it but still not really nice. Hmmm... I started as early as I woke up, after my breakfast. Seriously, I have problems mixing the colours to the colour that suits it. Tough! Painting is even worse. The colours are not even! :O I just hope I could finish a new piece of it on time tomorrow. All the best to me. :)
