I really like the art on the oldest 5-10 pages of your gallery. While your art did improve since then, it's a shame that you don't make that kind of art that often anymore. I hope you'll start making more of that again.
Everything after page 33 looks great. It's also because the newer pages are cluttered with pins, stickers, character sheets, sketches ect. While it is not a problem they are in your gallery, they shouln't be in your featured folder imho. These things are more important for your followers, not newcomers to your page. Followers get all submissions in their inbox, while newcomers first look at the featured art.
