This piece is decent, it doesn't seem to challenge you too much, but it still effectively conveys what you are trying to go for, so good work. Your linework here, while appropriate, lacks style. The most effective way to create a good visual sense of style with linework is to work with more organic shaped, and to vary the linework thickness throughout. Your image could be improved with more work on the environment, there isn't much happening here to compliment the piece. You might not need to add too much, but something simple to help balance the colors and lighting would significantly compliment your piece. Keep up the effort, and thanks for sharing your work with me!
