I am a bit late to the party but i am here now
I think both of your test shots are great and both look good to me
I often shoot in jpeg so you can get more on a card and you dont eat up space on your hard drive, if you want to or need to do a lot of work in photoshop and lightroom then it has got to be raw to give the maximum file information to start with, if you are happy with a quick crop and one click fix for levels and the like then jpeg is ok
so if you want acceptable photos to keep and post on the forums then use jpeg and if you want to upload photos to certain web sites, enter competitions, or potentially sell your photos then it has got to be RAW
I have never been a big fan of photoshop and would not pay out for the full photoshop cs package but i do use a version of elements that came free with a sony viao laptop, i could never spend two hours per picture tweaking them in photoshop like some do, I consider photography as a hobby and take pictures for my pleasure and occasionally to share with forum members I don't want to make money from my pictures so most of the time jpeg is good enough for me
