I like the contrast here between the delicate flower and the rough, heavily textured ground The narrow DoF is also bang on, and the composition here makes good use of the rule of thirds The colour scheme is good too- the white/grey vs. green goes really well IMO
An interesting picture...The daisy seems to be facing away, like it's moving on...I like it <3 The only thing that bothers me is the line of focused stone across the middle, it seems almost out of place, like the contrast between blurry and focused is too strong :]
The depth of field in this is gorgeous and highlights the texture of the petals and the road very well. The only thing I might suggest is that you make it a tiny bit brighter and add a little contrast. Anyways, this is very lovely. Nice work!
