Hey there!!
Welcome!!
You artwork look pretty nice!! I would suggest some things to get it even better!
I do think some situations the characters don't highlight enough from the background:
Example:
In some situations you highlighted more the character by giving them a thicker outline! That can be one of the solutions.
But what I Really feel what would improve a lot is some shadow working or coloring!
You can color it in a greyscale do give some depth to the scenes and highlight more the characters or the situations in matter. This would make you art take the next step!!!
But personally I can't stop imagining how cute your comic would look colored! But this is the other way you could go about the coloring part. If you feel you want to stay in a greyscale think about making some special episodes in color! I think your readers would really like it :D!
I think your going in the right direction.
Your art looks really good and you characters are pretty nice too!
GOOD LUCK!
