i love the greenish yellow on the first two. when you step back, there's a completely haunting feel to it. i don't really have any critiques to be honest.
the bananas look great, and the thick globs of paint make it look real painterly, mainly digging the specular lights all over it. makes me wanna eat it, no joke
and i really dig the hearts, very realistic and well done, especially the color of the shadows. when you back up real far it's almost photo-realistic.
as for the girl, did you sketch her originally from reference? at first glance, the anatomy seems fine, but then it almost seems like her chest is forcing itself to turn toward us while her far shoulder is pulling back. her face sorta flattens beneath the nose. the skin tones are great though, nothing too obscure and they keep that fleshy texture just fine.
man, makes me wanna paint. i'm a critic i guess, but i can't paint very well myself. anyway, keep at it amigro
