Violet Parr, There is a LOT of great stuff happening in that comic page! I know my way around a comic page, and the fact that you have a unique panel arrangement and that you took the time to ink it is awesome! I know how long that takes! Your poses have a great deal of action and life to them!
Here are some suggestions for next time.
Anatomy: The human form is the single hardest thing to draw period. Your figures have a LOT of energy and life, but to the trained eye small things like arm length and hands stand out. You’ve done VERY well “from memory,” but you are ready to move on to the next level and study “real” anatomy. PIXAR’s figures are abbreviations of real people, but you can bet that every artist there knows anatomy pretty well. Two of the best resources to learn anatomy from are :
Drawing the Head and Figure by Jack Hamm, and all Hamm books. Hamm teaches how to imply, or abbreviate people and everything else for pen and ink. I cannot tell you how valuable his books are. They are CHEAP too! The figure drawing book is only $9.50 at amazon!

Dynamic Figure Drawing by Burne Hogarth. This is a book that will show you how muscles interact in both men and women, but what makes this one special is that it will teach you how to construct the figure in three dimensional space! The drawings in the book are really exaggerated so they are very clear.
Backgrounds: First, let me say I love your backgrounds. Backgrounds are the bane of many art students because they always take longer that the fun stuff like figures. The main issue I see here is perspective. There are lots of great tutorials on the web and some $10 books on amazon as well about it. Like well structured figures, perspective is one of the foundations of good art.
Inking: Here is something I know well. I see you used marker to ink this page. Markers can be good, even great, but to get the precision and variety of line you see in professional work, you really need to use a brush. I use a Windsor and Newton 7 series watercolor brushes and Speedball Super Black ink. The variety of line thickness one can get from a brush is unrivalled. These brushes are fairly cheap at Dick Blick’s Art store. You need to buy several, as each brush will only hold its point for a few 11x17 inked pages.

An equally valuable inking tool is the Crowquill dip pen. Like the brush, it offers an extremely fine and precise line that you can vary in thinkness as you go, unlike a marker. I use the #102 nibs. Buy about ten nibs and a holder and some Speedball super black and you should be good for awhile.

Erasers: I noticed a lot of pencil left on your board. Though that is fine if you are making a mixed media piece, but pencil does not reproduce well. You should have a gum eraser, a “pink pearl” eraser, and a white “magic rub.” The gum is used for big erasing sessions, like when you are done inking a page, the Pink pearl is for dense, dark pencil so you can press hard and not tear the paper, and the magic is for erasing over ink as it will pick up the ink and not smear it.
Paper: I will stop here, unless you ask for more suggestions but you should try using Bristol paper for inked projects. It is a “cold pressed” paper with many layers pressed together to make a card-like very smooth surface that takes ink very well and does not bleed like markers. There are some cheap knock offs, usually marketed as “Comic Book Paper.” Stick with Strathmore 300 series and you can’t go wrong! The only problem is that they do not sell it in 11x17 (the standard comic book original art size) but you can get it cut down.

In any case, if you are still reading, I see great things in your work, and thank you for sharing it. I really believe you are ready to graduate to professional level tools! Good luck!
! And thanks for the suggestions, 
. Anyway, that’s all for now! Hope you enjoy! See y’all later 
… Thanks a lot!
