I like the naive touch of this one.

But I think you definitely should pay more attention to typography.
The letters are on the level of a shopping notice. Write more slowly and disciplined. Write letters with the same style as you draw an icon.

The line art could be more precise. You can get this better by simply working on a larger format.
If an A3-paper doesn't fit your scanner, scan it in two parts. But do it bigger.
