here it is in drop c as it should be:

d------------------------------------------|
a-14-15------------------14-15-------------|
f-------14-14/15/12--12--------14-14-15-17-|
c------------------------------------------|
g------------------------------------------|
c------------------------------------------|


but here is how it can be done in standard tuning:

e------------------------------------------|
a-12-13-----------------12-13--------------|
d-------12-12/13/10--10-------12-12-13-15--|
g------------------------------------------|
b------------------------------------------|
e------------------------------------------|
