I agree with all the suggestions. Your house is a little lost in the forest right now and does not look very welcoming, since you can't even see where the front door is.
If the big trees could be trimmed up a little that would help and get rid of the small evergreens. Then plant the shade garden not only around the golden maple but along the driveway (which is also the walkway to your door?) and in the space where the small evergreens are now. Most people when the put in plantings/beds make them too small. Then they are out of scale with the house and look like little dots here and there and the plants have no room to grow. Make a good sized bed, at least 3' wide through that whole area and don't try to fill it with plants, let there be areas of just woodchip mulch for awhile. The plants will fill themselves in, in a couple of seasons and look much more natural.
Along with the shade plants already mentioned, some other nice ones are ferns (lots of different varieties and sizes), bleeding heart, epimedium, hellebores, lady's mantle, lily of the valley, toad lily. Also spring ephemerals like mayapple, jack in the pulpit, trillium, virginia bluebells
If you want to put some areas in ground cover - there's ajuga it's grown mostly for foliage and the foliage comes in fabulous variegated purples and bronzes, does put up blue flower spikes in spring, or foam flower is a ground cover that also comes in variegated foliage and makes pretty flower spikes in spring, wild ginger which has very inconspicuous flowers, but fills in well to make a dense carpet.
I do always like to think about winter interest, but that doesn't have to be conifers. There are broadleaf evergreen shrubs, like azalea, moutain laurel (kalmia), pieris, daphne that come in very dwarf sizes. And there are flowering plants that keep their leaves all winter, like bergenia (pigsqueak), the hellebores (& lenten roses) and epimedium already mentioned, some wild gingers, candytuft, creeping wintergreen (if your soil is acid)
Then it looks like the side of your garage might be a nice sunny south facing spot, great to put in a cottage garden full of summer flowers or a veggie/herb garden. You can pick veggies and herbs to be very ornamental.
Have fun... endless possibilities!
