the colours stands out, i'll give u that. but for the first 2 photos, maybe the focus could be more obvious, but ur compositions are nice. =) thumbs up bro. P.S. did u photoshop any of the photos? 2nd photo looks like a little, enlighten me.
exploit the full potential of your lens. i believe its a 50mm rite? the depth of field can be achieved even better than this. so play around and i believe u will shoot alot more better photos. but overall well done.
