the 1st has a nice bg but is too monotone for me( i make monotone stuff but, w/e) 6/10 i love the simplicity 8/10
first: this oens the best of all 4, i dont like the stock that much but the bg is pretty nice. 7.2/10 the second is a bit bland and empy, maybe try some more stuff on that one, could work out great though 6/10 the third one is different, im not in for vector stuff myself but its nicely done 7/10 the last one is a bit monotone in colors. and the background looks badly brushed. the glowy bird brush doesnt help eitehr 5.5/10
