I would suggest maybe darkening the lines somehow, because I can't see anything on most of these, and for the ones I can see, Your shading is fairly nice, but you could try working on building frameworks for your drawings to keep the proportions regular.
I'd try different directions, other than frontward poses. You got dynamics down but it'd help if you corrected on your proportions. Do you use drafting skeletons by any chance? Those can definitely improve on more accurate anatomy. It surely help if you increased the darkness of your lines, if that's an adjustment that can be applied to your scanner. I like your subject matter though. Dungeons and draogns, plus, with the demons, I'm really enjoying what I'm seeing. Also I go try for various medias, if you haven't tried so already. Like inking. Usually an artist who's skilled with a pencil can usually be just as good -- sometimes even better -- with a pen. It takes time of course, but well worth it when the right skill has been gained. Take it from someone who's done it himself.
Keep on drawin' and improvin' on your work! Potential as yours shouldn't sit behind on getting better.
Well, I lack Photoshop, though, I have the next best thing; GIMP. Whenever I want to increase the darkness of the lines, I increase the curves. You should have an option in Photoshop which can do just that, if not better. After all, GIMP's a free imitation of Photoshop for folks, like myself, who lack proper finances. |3
Hey, good to see you again. Everything looks great, especially the last one. However... The Apocalypse's left thumb seems a bit out of place. If you fix that, it'd be more or less perfect, imo. In "Roronoa Zoro Rashomon" drawing, his left thumb (on our right side) seems to be "buldging" a bit too much. Other than those, everything else looks great to me.
Yeah, overall there's quite a few things wrong with the Apocalypse. I accidentally drew his arms freakishly short. I improvised a lot with it which is the reason for the proportions being off.
For Zoro, his thumbs actually looked that big in the original:
I felt his hands were big too, but I thought the angle and style made it acceptable.
Here's the finished version of the Joker I posted earlier:
But here's a questions for some of the artists on here, right now I'm using pencils to do the grey areas of some of my ink drawings. I don't like it. I know some artists use grey ink in the exact same way but will any kind of grey marker do? I just want to know so I can switch over.
I suggest you focus a little less on the details for a while and concentrate on anatomy. Also, spend more time with the preliminary sketches, and try looking at the sketches upside down to make sure everything's accurate before you begin filling in the details. Photo reference is also a very good thing, but you want to make sure you understand what you're drawing.
Some resources: Burne Hogarth's Dynamic Anatomy (you'll enjoy this one) Jack Hamm's Drawing the Head and Figure (focuses on females) Both of them can be found for decent prices on Amazon. Good luck!
