wow, really good for your first try (dont sweat the score, there seems to be a voting anomaly recently). id say: try blacklining, get those recesses nice and dark to seperate distinct areas (sword and hand, braceers and arm etc) id also say try and smooth it out a bit. i can see distinct brush marks. this might be because you are using your paints too dry. add some water to thin them a bit so that they come off your brush with ease. this will help with your blending. tip #3, post photos from farther away: focus wont be such an issue, and the small errors wont be so apparent. #4 lighting looks a bit harsh, and is making the transitions pop out, alowing us to see brush marks. good luck.
