these are pretty dang nitpicky but the red and blue lines on the right of the logo aren't perfectly straight or are cropped weird or something, similarly the bottom corner of the green and blue one look a lil weird too and not quite perfectly rounded off
also the bottom part where the green and blue brick meet doesn't seem to be perfectly aligned, but that might be the same problem as the very slightly slanted lines (edit actually it might be because the green one is like 1 pixel above the blue one i think)
also also there's a few spots not fully erased near the bottom of the logo
otherwise tho this is pretty solid nice work!
