I'm not sure what guide you've followed, because there are loads of different beginner methods. Personally I always orient the top two, three or four corners in the same way, using multiples of
R' D' R D (2x), since it's very easy to remember (although a bit longer to execute and counterproductive if you plan to transition into speedcubing in the future).
For your particular case it would mean the following algorithm (starting with yellow at the top, and red at the front):
R' D' R D (4x)
R' D' R D (2x)
Or completely written out:
R' D' R D R' D' R D R' D' R D R' D' R D U R' D' R D R' D' R D U'
Here is a video I created a while back with the Beginner's Method I personally learned. Starting at the linked 30:40 it covers orienting the top layer corners. I showed it with three corners, four corners, or two corners unsolved. Yours is the same as the one with two corners that I show at 33:37, although your corners are next to each other instead of kitty-corner of each other.
