Please help me identify this flower...

I took this picture in Queen Elizabeth Park. Anybody know what it is ?

 

More photos from Queen Elizabeth Park...would appreciate if anybody could tell me what they are.

And if you have any comments on any changes I could make to the composition or lighting of my photos, I would really appreciate it. Still learning !

Thanks,

Amber

 

looks like a close-up on an elfin impatiens, an annual in these parts.

 

Thank you !

BTW..sorry for the size of my other attachments. If you click to enlarge them, they really come up much larger than I had intended. I hope people can identify them from the smaller thumbnails.

A Dahlia, a Hibiscus syriacus (perhaps 'Blue Bird') and a Hemerocallis
