Ummm...how can he not love it That's awesome Can;t believe i never thought of this idea. Did the client provide you with the cover and the details or was it your idea? Seriously brother, good stuff
And i know you want critique, not just compliments, so when i find something i think doesn't look right i will comment. For now though i honestly think all your work i've seen has been flawless. Not sucking up, just honest I'm a writer, not an artist, and prefer critique to just compliments all the time. It's the best way to get better Have a great day.
