Hey that's some good quality stuff, I like it all (especially swimsuit
haha jp, good job though. Just as a suggestion I think you should try to add some more contrast in your pics, with some deep blacks for the really dark areas...I've found that my newer pictures look much better than my older ones because I've concentrated more on getting good contrast, and there's an obvious difference. So yeah I think that could help improve your stuff, because it already looks good and I'm sure will only get better as you learn new things.
My picture is of my cocker spaniel, Skittles. Ofcourse even the stuff that looks finished isn't necessarily finalized yet, but here's a comparison.
