It's an Aster of some variety - you say you've touched up the image, so this may not be the exact variety because I don't know if you've changed the colour, but its Aster novae-angliae, possibly the variety 'Barrs Pink', though there are probably somewhere towards a hundred specific varieties of this plant. If you have altered the colours, it's probably best to stick to Aster novae-angliae and not give a varietal name.
UPDATE: Now that I think about it, it could be Aster novi-belgii, another group of Asters... so you might just want to stick to the name Aster since I can't identify the exact variety.
