In the Cartesian coordinate system, the parametric equation of line $l$ is $$\begin{cases} x=-1+ \frac { \sqrt {3}}{2}t \\ y=-5+ \frac { \sqrt {3}}{2}t \end{cases}$$ (where $t$ is the parameter). Now, establishing a polar coordinate system with the origin as the pole and the positive half-axis of the x-axis as the polar axis, it is known that the polar equation of curve $C$ is $\rho=4\sin\theta$.  
(Ⅰ) Write the standard equations of line $l$ and curve $C$;  
(Ⅱ) Given that point $P$ is a moving point on curve $C$, find the minimum distance from $P$ to line $l$.
