stuck inside has a nice moody vibe to it, while let me through has a more chaotic vibe--both due to the use of color and lineart. stuck inside also does a better job of portraying what it is meant to represent imo since foxy's details do get a bit lost in let me through (i dont know much about FNAF gimme a break)
i do prefer stuck inside as i quite like the moody atmosphere and the simplicity. let me through isn't to my tastes but it has potential for a good rework, i'll gladly give my advice for a redo if wanted
overall, good work! you clearly enjoyed the process and you should show off the product. keep drawing, don't be like me and stop lol
