This artwork has a lot of small details, anatomy seems Ok, perspective is really cool, but you shouldn't be joining the beginner category, this artwork is decent for lvl99 regular category, by joining the beginner category you are just crushing chances of wining for people who really ARE "beginners". That's why its called "Beginner category" after all, so people who draw beneath "line of decent artwork" can win something, this is obviously above it, just compare you're entry with other entrys from b-lvl99 tag. People are always learning and i dont think thats an excuse to join the beginner category. But still, nice job on the artwork, i like it.
