I'd suggest messing around with line width, tapering and such instead of keeping a single width.
Maybe more distinct shading and highlights as well? It's a bit hard to see where the light source is in some of your pictures, but overall it's solid. Playing with the color of shading can do wonders as well, and is sorta in tandem with the intensity of the shading. Like, shading with blue/ dark red/ whatever can make a picture pop a bunch more than just a darker shade of the base color. Perhaps also fiddle around with more dynamic posing, since a lot of your gallery seems to be standing around (not that that's bad, just the more variety the better yanno?).

Yer real good at expressions though, always been a tad jealous of that. I can always tell its your drawing by the eyes and face.

dang these are all good points yeah

the shading i have been trying to work on but thats more of a brush choice problem right now

Line work is similar situation and i doooo wanna try more of it, shaky hands can be a pain though.

Poseing is honestly mostly my own fault yeah, i'll always get kinda worried that they dont look right and end up defaulting to that. Really gotta work on that for digital work.

As for the expressions I'm glad you think that! That was one of my goals for getting better at the past year so i'm glad it's gone well!

Yeah I feel you on the shaky hands, that can make any funky line-related stuff a pain. Do you use SAI? If you do, I use the S-7 stabilizer and it is an absolute lifesaver. It can be sorta hard to get used to, but it gives really smooth lines and width variety.

i'm at S-3 for now yeah

Maybe try a higher level? I just compared em and S-3 feels very different from S-7.
Not everyone likes the aesthetic of em, but thicker lines are also an easy way to make lines look neater. They also allow for more notice tapering.

Your Colors
You should learn a bit more about color theory, since the colors you pick tend to not look very good. (They're typically over-saturated, or don't mesh together well)

Here's a useful video on the subject (I highly recommend it)

Or if that's not your thing, here's something somewhat similar (but less detailed) in deviantart-esque tutorial form.

Shapes
You've probably heard this before, but it's very useful to break things down into their basic shapes to understand how they should look or be drawn. It's even more useful to figure out how to break down things into three dimensional forms. Everything has volume and takes up mass. I don't exactly have any tutorials or anything for this, sorry! (Side note: It's also really good to understand mass and volume when shading.)

Anatomy
Understanding human anatomy is a huge part of drawing, wouldn't you agree? It's also useful to know canine anatomy and such, but since human anatomy comes up a lot more frequently in your drawings you're going to want to learn that first. It seems like you already have some grasp on it, but not fully. I'd recommend using a lot of references (wouldn't be hard to find if you search for 'human anatomy references' on google) If you want some books on the subject, I'd recommend "Drawing the Head and Figure" by Jack Hamm.

I don't have an exact preference of what you draw more of, just do whatever. I do hope these points are useful to you, though! (They're just things I noticed while browsing your gallery)
