A very cute Pokemon Nekomajo!
I do agree that the art isn't top notch, but all good artists have to start somewhere, right? I remember drawing like that at one point in my life and remembered the 3 P's: Practice, Practice, Practice!
What I would do is study the anatomy of anime characters and practce drawing that. Bathing suit and/or nude pictures help best in that category but you could skip the nude pics and just use bathing suits and clothed people. Not all clothes are that tight and next to the skin, give it some looseness and maybe some folds.Find a picture of your favorite anime character and draw what you see (Don't trace!).
With the 3P's, anyone can improve.
With me for an example (oekaki pictures):

Now, I find this uber,uber,uber crappy in my eyes

And I kept using the 3P's and improved...
Just don't get discouraged and keep it up! :D
