Yes, It's true! This is my third work in pixel and I still have much to learn :)
And man, your gallery is amazing O_O
Good idea and the execution is not bad.
The weakest part is the tongue, it's edges are rough and angular, and the width is not consistent.
like it a lot, you did a nice job on the little details like the lighting on the edges. Only thing that seems a bit off is the positioning of the centre round holes of the tape (aren't they positioned too low?)
