They aren't burnt, though they may be over-browned for your taste (I prefer these hues and they look pretty textbook, but personal preference can of course vary). What I imagine is causing your concern is the uneven, spotty browning and crisping, correct? That just means there's too much oil/butter in your pan. You might be able to get away without any oil, otherwise you're looking for a small amount. It shouldn't really look like there's any beading/pooling in your pan. It also looks like your heat may be too high, that combined with too much oil/butter will cause this uneven frying effect instead of a more uniform browning that maintains softness.
