the top one i prefer v2 it needs a clean up session tho and some flow :D but good depth... its a lil dark but with the right lighting i think that would be fine!
The second on needs depth and quality... i dont particularly find the colors attractive, but thats me... and also i would add some layers to help it from being over contrasted... with the right smoothness and with some burn/dodge, and without the sparkle and fractal layers that could be a yummy tago :)
EDIT: I wanted to show u what some filters could do... granted I used topaz and most ppl dont have that but with cs5 u could use smart blur, vibrance, and saturation/hue filters -- Looks weird with the other fractals on it... lol :D
