Hey that's not bad!

The only things I would say you should work on is making your lines smoother, and making your colors blend better.

Updated OP, anyone with coloring tips please speak up

The lining is pretty decent it gives you a unique style
your coloring and shading also give this feel off
but I fell when you colour you forget to finalize
certain lines and shades... Not saying to stop colouring
just pay attention to the piece as a full before finalizing.

Updated the 3rd as finished, want to pose a question:
Should i do realistic backgrounds for my images?

new wip

Ay man these are really nice I would say work on making your lines smoother
and your lips actually almost connect at the ends.

you should really work on the lips with the 4th pic

also you should start shading.

tips on shading?

I have too much to critique on the final results, but first, dont draw on your phone, you will never get a quality drawing on a small screen, believe me.
