Fist in Blue

Tomorrow is my faculty test to admission for SADM in NTU, so I sketched my left fist to see if I still can draw, after resting for such a long time. I think it is a 10 - 15 minutes sketch but I dun really know cos my concept of time is always lost during drawing. Just did it as quickly as possible since it is about 15 minutes a question according to the test syllabus. Wish me luck!
