That's nice! I like the style and how expressive your characters are. Also you use a lot of different angles and plans which gives an interesting look to your drawings.
For things to improve, I thought at first of colors, that would give a whole new dimension to your drawings. After second thought, I realize that there are some issues with proportions on your characters and I think that would help the readability to your drawings.
I also noticed that all your drawings tell a story, and that's really great! It really has a narrative feel
I hope it helps! Keep up the great art!
