Sweat Peas help

[cherry916]

I planet some sweat peas awhile ago and I'm worried about it. This ws the first time I ever planted them and the plant it grew but then it seemed to just stop and the leaves, it just doesn't look right to me. I don't know if it's the ants that invaded the ground near it or it's not getting enough water I really like some feedback.

In the meantime my sunflower just bloomed. It's a hybrid mix












I tried to  get as best pictures as I can but my camera sucks and again my sweat peas are really tiny. Are they fine or is something wrong? If so what can I do to help it along?
