Wow wow wow, calm down there buddy. Boards are a great place for feedback because of anonymity, and will never turn into a circlejerk unlike most places on the web. And ofc gay animals will make you look like a freak if you try to show it to people IRL, no matter how talented you are.
Internet is like communism, everything belongs to people here, including art, so "ruining characters" isn't about copyright or any of that artistic butthurt, but the purist mentality. Let me explain:
When people consume media in any form, they get attached to certain characters either because of their looks or personality. So they start asking artists to draw those characters because they crave for more of the same. By taking designs created by other people, you automatically agree to follow those designs, unless you want to create something entirely different. If artist changes something to the point where that particular character is unrecognizable anymore besides the name slapped on the picture, then nobody will attach to that work of art, making it bad overall, even if technically it's amazing. Simply put: design > execution. Appealing to the audience > artistic vision.
Now to the technical stuff. There are only 4 pillars here, the four elements of any drawing, from easiest to hardest:
1. Line work. That's where any picture starts, anyone can do it correctly unless they are missing both hands. You have reached the point where you are better than most amateurs at this.
2. Coloring. The next step is a little bit harder, and requires a basic knowledge of color theory. Judging from your pictures, you already know it well enough.
3. Anatomy. That's the point where amateurs are separated from the pros. It takes years and lots of practice, and most importantly, you have to study every object separately before you can draw it correctly. As you have noticed, the biggest problem with anatomy in your pictures so far are paws. So to make them more appealing you have to either focus on drawing paws over and over until you get it right, by copying reference images found on the internet, or simply abandon ship and cover character's feet in every drawing, by putting them behind objects (trees, grass, water, rocks w\e).
4. Shading. The most time consuming task, which requires not only artistic skill, but also deep knowledge of software\hardware you are using. The best of the best are usually those who mastered shading to the point where they can cover any fuck up they made with a few filters, and use light to their advantage, focusing the viewers attention on the stuff they draw best. I would advise forgetting this for a while, until you have learned anatomy, or played with designs to the point where you feel like you've achieved enough viewer satisfaction, and now only technical part needs improving.
Speaking of image resolution: it's not very important, but personally i would like to see all images in generic resolutions such as Full HD, 2k or 4k, if you have an expensive monitor. It's no big deal, but lots of artists, even those who have the skill and money, are constantly forgetting that digital art should be future-proofed in a world of constantly advancing technology. It's a real shame to see those 800x600 drawings from some years ago on a modern screen.
And the last one, a personal wish: Try to draw any character from the game with their original outfit\armor, and don't forget to do something with the paws. It may not be as amusing to simply copy the designs, but since every artist has a unique art style, looking at it is very pleasant just for comparison. If there are too many details, and it's too time consuming to do, you can always get creative, and make it look like the lost something or it was destroyed, just to work less without looking lazy in the end. I wish you good luck, and really hope that you will keep improving, until you manage to create that unique style, that will be recognizable by others. IMO art is damn serious thing, even as a hobby, because it allows to bring joy to countless people all around the world from the comfort of your room, and if you are good enough, immortalize it in the depth of the internet, while getting that happy tear when you go to sleep, knowing that someone spend their time to save it to their hard drive. Keep it up, and may autism be with you.
