Style is something that changes and shifts over time, I know many artists with very similar styles. As long as you are not purposely duplicating someone’s style exactly most people don’t really mind, it’s just a part of art ^^
Airbrush white paint lightly over parts of your artwork to create a glowing highlight or the effect that a part of the picture is further away.
When starting an art blog decide on what look you want and how to show off your art, choose a color scheme and make a good icon and URL based on this. So if you draw super cute art you might use pastel colors and lace etc. and have a URL about sweets or just your artist name. If your art is darker you would have a dark, usually monocrome (one color plus black white and gray) color scheme.
:3 thank you very much!
