Looks good for a first-timer.
You say, though, that you didn't sketch it. Although it may seem reasonable for a beginner to copy poses exactly as they see them in their reference images, it might help if you try and mentally analyze the way the characters are structured. What simple shapes and divisions are put together to make the character who they are? If you can figure out how these parts can be manipulated into different poses, then you'll be able to do more with the character than you would just copying poses.
That being said, you're still off to a great start; don't be discouraged and keep at it!
