Thanks for the pics! The split level does make it a bit tricky.

I agree that the front entrance should be welcoming. I did a little research on the front door/bay window dilemma and it seems like a good idea to take the first impression off of the bay window. Here are some inspiration pics you might like:

If you want to continue a front porch (even though it will darken the windows on the bottom level), this is a perfect solution. Important to do a very large front door with sidelites or double door. A porch is never a bad investment. Notice the curves on the porch soffit and the simple straight roof line. Good balance of all elements.

This version would also adapt to your home nicely. I love the little "bird's eye" over the front door. This mimics your roof line and the front door is detailed with a center hanging light, double doors, and overhang.

Here's a good front single door. My feeling is that it should be dark brown or black or natural wood finish.

I like this one very much and could be stunning on your home.

This one shows a peaked entrance which I noticed on English homes. It doesn't have to be so many peaks like this house (I think it's too much) but the relationship of the front door to the bay window is good with the dark wood front door and curved entrance portico.

Call a local architect!! Any changes to exteriors in your town may require approval from the town you live in, may require drawings/permits as well. It's a thing worth doing well to achieve a harmonious look, and one you will be happy with for a very long time.

You have many good suggestions upthread about a covered structure. Some other possible fixes:

--Extend a white pergola to whatever white porch structure you add. Plant a climbing plant on the right to grow over the pergola.

To balance the right side of the house:

--Add a tall cypress to the far right side of the house

OR:

--plant a tree in the middle of the right lawn.

--Extend out a round, much bigger bed of plantings on the right.

--Paint the front door a bright yellow or cobalt blue.
