So looking at the the first page of work on your art page I see that almost all of your work is done in pencil and looks very unfinished. It's harsh to say but this is not portal worthy stuff. Your drawings aren't bad at all, they do have personality and the ones that I have looked at have some interesting poses going on, but you need more complete pictures, right now as stated they're all pencil with very minimal shading, their value scales are not very extreme and the handful that I looked at have a ton of white space. These aren't finished pieces, they're refined sketches. Throw some color on them or some ink or if you want to stick with pencil get some more contrast in there, really go hard with the linework and shading, give it some pop and give them some backgrounds. You can do it, it's just a matter of taking the time to. The art portal should be a showcase of your best work so put your best foot forward. Hope that helped in some capacity.
