Take my hand

Holy flaming balls I'm uploading something! In my absence I've been practising a lot with my regular drawings and this one was mainly about testing my shading skills. Despite the flaws which I already know about (Hand looks goofy, left arm seems too small ad I just got lazy with everything above the shoulders) I honestly think this is some of my best work and that the shading works really well. I know it's not great but for someone like me who never really had an interest in art and never took a class, it's not half bad.
This is my OC Nate Wollf (Hahaha Mary Sue.) Who may be appearing in a comic that I might be working on. Not giving anything away *Winkers*
I'm not looking for critique (Because I'm a bitch) but general opinions and advice would be really helpful. Cheers.
