I like it, its simple a fun to look at, as for criticism maybe practice your anatomy a bit more, if you're interested in that I suggest these books Draw comics with Dick Giordano, and how to draw comics the marvel way, there's also many you tubers who cover this in greater detail like Proko who will teach you everything you need to know about anatomy, and the box office artist for a more dramatic style. Hope this helps and keep up the good work!
