singstar10 an artist trying to find a style

I definitely like the style with a black out line more so than the last one. ^^

 

Hi!
I think you should stick with multiple styles, they tend to add a lot of variety in your work without being bored with your pieces; many artists tend to use multiple styles/mediums in their pieces (for experimentation and like I said before, variety).
I think what you can work on is your lineart, right away your lines are really jagged and they don't make your overall pieces look clean. I fully understand that lineart is really difficult to master (especially in digital art) but I would probably focus more on that and have a lot of patience/practice with it.
The anatomy is a bit off for many of your pieces, more so in your Pegasus one (i.e. the wings aren't connected to the shoulder blades and half of it is cut out; don't be afraid to made the canvas bigger if you are running out of room). Anatomy is also quite frustrating too so maybe you could have reference images for the poses you want and then copy the posing (you could also have a friend strike a pose for you and copy the outline of it).
Anyways, I hope I helped!
