Colours of the 1st, and composition of the 2nd for me Adele.
PS: I think your images would look a lot better if you were able to post them at larger resolution too Adele. Try 640x480 or even 800x600 - will yield better results, especially on web pages. Just a thought....
Looks the same to me too Adele. I see you use flikr to host your images, sorry but I don't use flikr so I can't advise I'm afradi, though I am sure there's a way to have images at a slightly higher resolution that you currently display.
The other options are to;
1 - host your images on the free gallery space you are provided with on your talkphotography account here
2 - use some other image host service. I use photobucket - free, and comes with heaps of space
Also - what processing app do you use when you get the images out of your camera? Are you saving them at a certain size before you upload them?
Nice shots, I think they would look better had they not been cropped so tight, I like the colours in the first.
looking at your flickr site I am guessing that these shots have been cropped quite a bit, which is why they are not showing any larger.
If you are cropping try not to crop an area less than 800pixels on the longest side.
