This is my first critique yay!
So yeh It's good but it can improve (like my art XD)
It kinda reminds me of Pokemon Sun and Moon?
The drawing is good but the coloring is a bit rough and messy, try coloring very lightly. The hair seems to be a bit too symmetric, for ideas you can google "Hair Adopt." That's how I would do it anyway.
The inking is also slightly messy. Try relaxing your hand in some sort of way, and don't lift the pen up and start again (common mistake).
Try to draw a little white dot in the eyes to make them look natural, and I would draw the eyelashes on the sides (but you can draw them like this too it looks nice)
Btw I visit the Manneken Pis everyday! (Wow guess where I live lol)
Conclusion? Yay practice!
